For further details about how these taxes are applied, visit the link: http://en.wikipedia.org/wiki/Sales_taxes_in_Canada.

Simply put, a Direct Inward Dial (DID) number is a virtual number that works just like a regular phone number, except for the fact that it is not attached to any POTS line (landline). Once your configuration is ready, you can be reached at your DID number from anywhere in the world, just like any other phone number.

VoIPXtreme is a BYOD (Bring Your Own Device) provider, which means that you get to use your own hardware and are not obligated to get your equipment from us.

The cost varies depending on the services used. For outbound calls, the cost is subject to the per-minute rate for the destination called and the billing increment. For inbound calls, the cost is subject to the rate plan of your phone number (DID), the monthly fee and the billing increment, if applicable. There may be additional monthly fees or setup fees, depending on the services to which you are subscribed. For more details about the cost of the service, visit the following link: Service Costs.

We do not charge any cancellation fee of any kind, you are free to cancel your account or number at any time you wish to.

Yes. VoIPXtreme allows you to change the billing plan of your US and Canadian DID number(s) whenever you wish. The plan can be changed on the Customer Portal without needing to contact technical support.

With VoIPXtreme, there are no “local” or “long-distance” calls. Each outgoing call is charged according to the per-minute termination rate for the destination called. Due to the advantages of VoIP technology, the rate for calling any given number will always be the same, no matter where you are when you place the call.

VoIPXtreme provides all the necessary tools to calculate expenses with no room for error. It is also important to remember that inbound and outbound calls are billed separately. For example, the cost of the flat-rate plan for a US-based DID number could be $4.25 a month and $0.00 per minute for inbound calls, whereas all outbound calls will still be charged as per the termination rates. For example, calling a US48 number is $0.01 per minute.VoIPXtreme works as a prepaid service provider, and you must deposit a minimum of $10 with a minimum threshold of $5 in your account to be able to send and receive calls.

Before receiving incoming calls, you need to order a DID from our stock by accessing your Customer Portal. You can also port a number that you previously had with another provider. For numbers in the United States and Canada, we offer two types of plans: a monthly flat rate or per-minute rate. As for outgoing calls, our billing is on a per-minute basis and, like any long-distance phone plan, the cost depends on the destination. You can access our detailed per-minute rates for different countries at Rates.

At VoIPXtreme, we charge for calls based on six-second increments. This applies for all countries except Mexico, where a sixty-second increment applies. A billing increment is a unit of measurement of call duration expressed in seconds. One minute is divided into ten periods of six seconds each. For a rate of $0.50 USD per minute, the user will be charged $0.05 USD per each six-second period. In other words, $0.05 USD x 10 six-second periods per minute = $0.50 USD per minute.

The billing of your toll-free number depends on the country in which your number is based (the United States or Canada). For a US / Canada toll-free number, there is a monthly charge of $2.99 and a rate of $0.030 per minute for inbound calls. For a Canadian only toll-free number, there is a monthly charge of $2.99 and a rate of $0.030 per minute for inbound calls.


There is a one-time setup fee of $2 for activation of the E911 service and a monthly regulatory fee of $2.00 per activated DID number. if you decide not to take the monthly 911 service and if there is a call for 911 it will be charged at $10/call for each 911 dialed without a plan.


The Virtual Fax feature is used for sending and receiving faxes (facsimiles) with the VoIPXtreme service, using a dedicated DID fax number. A DID fax number can be acquired on the Customer Portal in the Fax Numbers section under the Order DID(s) option from the DID Numbers menu. Regular DID voice numbers are not compatible with the Virtual Fax feature. In order to use our Virtual Fax feature, you will need to purchase a Virtual Fax DID number from our list of numbers. A DID fax number has a monthly fee of $1.99 with a per-minute fee of $0.029.

As they are different routes, Premium and Value routes offer different qualities of service and different rates. For example, the Canadian Value route offers some of the greatest rates on the market: the rate for outbound calls is $0.0052 per minute for most of Canada. This is a very good option if you are looking for the best wholesale rate to pay or to offer in case you are a reseller, while keeping a very good level of quality and reliability. As for the Canada/US48 Premium route, you pay flat rate of $0.01 (1¢) per minute for all of Canada and the continental USA. VoIPXtreme uses Tier-1 termination carriers for this route. While this route has a higher per-minute rate, you enjoy the same level of quality and reliability on every call. It is important to note that while the Canadian Value route usually delivers good results, the Premium route will consistently provide great results. As for international calls, VoIPXtreme also offers Value and Premium options. In this case, there is no specific rate; different countries will have different termination rates. In some cases, you will find the Premium route less expensive than the Value route.

There are different types of DID numbers. They are mostly differentiated by their geographic presence.The types of DID numbers most commonly used by our customers include: Local DIDs from the United States or Canada International DIDs Toll-free numbers For more information about getting a DID number and other types of DID numbers, please see our related article Order a DID Number

Caller ID is a telephone feature that transmits a caller’s phone number to the call recipient’s phone. Where available, the caller ID number can be supplemented with the caller’s name (e.g., John Smith). There are two types of caller ID: caller ID number (CID) and caller ID name (CNAM). The caller’s phone number and subscriber information may vary depending on the location and the information on record with the carrier.

CNAM stands for caller ID name, which is the information that will be displayed on the call recipient’s phone when you place an outgoing call. If you will be making calls to Canadian numbers, you can simply pass the caller ID name from your device or system, as most of them support this. For calls to the United States, the caller ID name works differently. In this case, it is controlled by a national CNAM database with records of numbers and names matching each number. We can update the CNAM database upon request. For more information, please see our related article at Caller ID Name.

We don’t provide any hardware or software for using the service. This is a BYOD (“bring your own device”) service, which means that you are free to purchase the IP phone that best suits your particular needs. This is in contrast to providers that require their customers to purchase specific phone models to match their technology or even to purchase phones from them directly. You can get any type of IP phone from any communications specialty store. We also support all SIP-compatible devices.

Due to the nature of troubleshooting, which can prove time-consuming, we have opted to provide support via a ticket system (email) and live chat. At this point, technical support is not available over the phone.

We offer E911 service only for US and Canadian DID numbers (including US and Canadian toll-free numbers). This feature can be activated directly in the Customer Portal by accessing the E911 page from the DID numbers menu. More information is available in our related wiki article here E911.

We do not offer a calling card feature at this time. However, you can set up a calling card solution using your own system and our DID numbers, as long as the corresponding DID numbers are under our per-minute rate plan. You can also use our DISA feature, which allows you to set a number for our system to call, in order to receive a dial tone and place outgoing calls through the VoIPXtreme network. Just like a calling card, this feature is useful if you want to make a long-distance call from outside your calling area or if you don’t have a VoIP device readily available. For more information, see DISA.

We offer a virtual fax feature This feature can be used with special DID fax numbers, which can be acquired and configured through our Fax Portal for customers in the United States and Canada. It is also possible to port a VoIPXtreme DID voice number or a number from another provider into our virtual fax service. To port a number from another provider, simply go to the DID Portability section of our Customer Portal. For VoIPXtreme numbers, you can request an internal port by emailing our LNP department at Ports VoIPXtreme. The porting fee is $15 per number for both options. Note: This service can only be used to send faxes within the United States and Canada at this time. We cannot guarantee that international faxes will be properly received. Virtual DID fax numbers cannot receive regular voice calls or SMS messages—only faxes. Please see our related article for further details: Virtual Fax.

We do offer SMS service. SMS is available for a great number of DIDs and cities across the United States and Canada. The SMS service is available through the customer portal and also via SIP protocol from a supporting device or software. You can read more details about this feature in our related article SMS.

We do provide audioconferencing for our customers with a dashboard to manage and record the conference.

Our main offices are located in Montreal, QC, Canada. We also have a technical site located in Merida, Yucatan, Mexico, for the Latin American market.

The referral program allows you to receive VoIPXtreme credits for every friend you refer. The more referrals you make, the more credits you make. In order to get your credit, your friend has to open an account, deposit funds, make their first phone call and funds will be automatically added to your balance.

Yes. With the Ring Group feature, you can have incoming calls redirected to multiple destinations included in your Ring Group, where a member of the group is able to answer. When a call is placed with a DID number routed to a Ring Group, all members of that group will ring at the same time until the call is answered by one of them. You can add various types of members to a Ring Group: Main Account, Sub-Accounts, SIP URIs, Call Forwarding. You can also select which voicemail should be used by the system in case none of the members answer the call. The maximum number of members in a Ring Group is twelve: up to eight SIP, IAX2 or SIP URI members and up to four call forwarding entries per each Ring Group.

Due to the nature of the VoIP technology, a VoIP phone is capable of working just like a regular phone and even more, which means that you can place a call anywhere around the world on any mobile device(e.g., laptop computer, cell phone or tablet) carrying your same number at a much lower rate than youwould pay if calling from a regular landline. Furthermore, you use the same dialing format as you would from a regular phone to make calls. One of the great advantages of VoIP technology is that it enables free calls in many different ways by making use of each provider’s internal network capabilities. You can access the VoIP Customer Portal to check rates for incoming and outgoing calls for Canada, the United States and international destinations. You can choose between a flat monthly price or a per-minute rate plan for incoming DID numbers.

For your basic equipment, you need an IP phone or softphone or any other phone equipped with an ATA adapter. Since VoIP technology works with over the Internet, you will also need a high-speed Internet connection. If you wish to set up a company system, you will require other devices such as an Internet Protocol Private Branch Exchange (IP PBX), several lines, several routers, Virtual PRI and a PBX server. If you are using a softphone, you will need a VoIP headset and a computer or smartphone to make it work.

Yes. In the United States, all inbound calls will display caller ID with name (also known as CNAM), as long as the caller’s name has been added to the number on record in the CNAM database, and provided the call recipient’s DID number has the “Caller ID Name Lookup” setting enabled. In Canada, CNAM works as long as a valid caller ID name is being transmitted from the caller’s phone system. **It is important to note that while CNAM works with calls inside the United States and Canada, it will not work for international numbers.

Yes, we do support sub-accounts. Sub-accounts make it easy for you to share your VoIPXtreme account and make it more versatile. With sub-accounts, you can use multiple devices on your account.

Yes. VoIP offers a vast range of telephone numbers in many different area codes. Simply access the Customer Portal to see a list of available numbers. This solution is often preferred by customers who wish to make calls to or receive calls from customers, friends or family members living in different cities without incurring long-distance charges or for businesses that wish to have a local presence in many cities.

No. At the moment, we do not support emergency 911 dialing outside of the United States and Canada. We recommend using a traditional landline or your mobile phone to make emergency calls when you travel abroad.

At VoIPXtreme, forwarded calls are billed according to two different segments: inbound and outbound. When you forward your calls to a number, the inbound segment of the call is charged according to the billing plan you selected for your DID number (per-minute or flat rate), and the outbound segment of the call is charged according to our per-minute rates for termination, depending on the destination of the call, for the same duration as the inbound segment.

Call queues are specifically designed to manage incoming calls. By setting up a call queue, you can have many callers wait on the line until an agent is available to take their call. If you configure an IVR for your DID number, you can make it so that callers first hear a welcome message and interact with a voice menu before being sent to the call queue. At VoIPXtreme, the Call Queue feature allow users to customize their call queues to play pre-recorded messages about their company, music or advertisements for callers while they are on hold. Various ring strategies can be established to determine routing patterns for each call queue, such as Ring All (ring all available agents), Round Robin (distributes calls as evenly as possible), Least Recent (sends the call to the agent who least recently received a call), Fewest Calls (routes to the agent who has taken the fewest total calls in the session) and Random (leave it up to chance).

A sub-account, also referred to as extension, allows you to register more than one device to your main account to make or receive calls simultaneously. You can also use it as an internal extension for your office or even your house. Many of the features within VoIPXtreme make use of sub-accounts. Each sub-account, or extension, is assigned a unique user ID and password, which are required to register their dedicated VoIP device or devices.

Toll-free numbers are special numbers that are designed to allow callers to reach certain numbers (often long-distance) without having to pay long-distance charges. These numbers are mostly used by companies who wish to allow their customers to call them for free no matter where they are located. There are several toll-free area codes, namely 800, 888, 877, 866, 855, 844 and 833. They all work the same way, but the choice of prefix depends on the businesses advertising strategy. Traditionally, 800 numbers have been used for television and radio advertisements, but other prefixes like 888, 866 and 855 are gaining popularity.

Virtual SIP numbers are similar to standard DID numbers. The major difference is that virtual SIP numbers are not accessible via “PSTN”. They can only be reached via “SIP URI” over the Internet. For example, if you have a DID number with another provider that supports SIP URI forwarding, you could forward your number to a virtual number at VoIPXtreme, just as if it were one of our numbers.

SIP phones, also referred to as VoIP phones or softphones, allow users to make phone calls over IP or traditional networks using VoIP. SIP phones can be software-based (where software applications are installed onto your desktop or laptop to make phone calls over the Internet) or hardware-based (where the phone works just like a traditional one, except that it makes phone calls over an IP network instead of PSTN lines).

Call Forwarding allows users to redirect incoming calls to another phone number or to a mobile device such as a cell phone, tablet or computer. Calls can be forwarded to any number around the world. With call forwarding, you can program your phone, Customer Portal or VoIP software to automatically forward calls to your preferred mobile device (cell phone, laptop, softphone, etc.) or to any number capable of accepting calls.

With this feature, you can set a number for our system to call back in order to receive a dial tone and place outgoing calls through the VoIPXtreme network. This is useful if you want to make a long-distance call from outside of your calling area or if you don’t have a VoIP device readily available. When a DID is set up with the Callback feature, calls that are placed to this DID return a busy signal, and the system calls back the specified number and provides the user with a dial tone to place an outgoing call.

Caller ID Filtering allows you to filter incoming calls based on their origin (such as private, anonymous or unknown numbers or area codes). For example, if you receive unwanted calls from a telemarketer or survey company, you can set up a filter for each of your DIDs to route those calls to voicemail, play a pre-recorded message or simply disconnect the call. On the other end of the spectrum, you can give preferential treatment to your favourite customers and route their calls to provide them with a fully customized experience.

The DISA (Direct Inward System Access) is a feature that, when configured with a DID, will allow inbound callers to access outbound call service through your VoIPXtreme account, similar to what a calling card service does. When you call, you will be prompted for a PIN number and the telephone number you wish to reach.

IVR (Interactive Voice Response) is a telephone technology that works just like a virtual receptionist. With this technology, inbound callers interact with a voice menu using their telephone keypad or by speech recognition in order to be connected with the proper person, extension or department. This allows customers to get the information they need without having to wait to speak with an agent.

Latency refers to the speed with which data travels over the Internet and through network connections to reach your hosted VoIP service provider. Latency and bandwidth are the two main factors that determine your network connection speed. When transmitting sound, latency can cause static, dropped calls and choppy audio.

Packet loss is defined as the failure of transmitting and receiving data (audio, video, computer). It often occurs when an Internet connection becomes overloaded with data or traffic. Packet loss should always be zero when your phones are in use, in order to avoid poor sound quality or echo or jitter when transmitting images. Packet loss can be caused by hardware or software problems, including cabling, but the main culprit is usually insufficient capacity of the network being used.

PBX means Private Branch Exchange. Basically, it is a telephone exchange system that manages a company’s incoming and outgoing calls and manages internal communications between employees. The advantage of a PBX is that you can equip your system with more phones than physical phone lines. It also provides a vast range of features such as call waiting, voicemail, three-way calling, call forwarding and other, more advanced features such as call queues and interactive voice menus. As for IP PBX, it is a software-based PBX phone system solution that allows remote or mobile employees to connect to the company phone system or voicemail, no matter where they are, as long as there is an Internet connection.

The Phonebook feature allows you to configure up to 500 Phonebook entries with caller ID name (CNAM) overrides and up to 99 speed-dial codes for those entries. For example, you can create a four-digit Phonebook entry to call your favourite customers or relatives. Additionally, you can use a caller ID name (CNAM) override to identify inbound calls from important customers, regardless of whether their number is registered to a proper CNAM central database. Phonebook entries are also available with our Virtual Fax and SMS features. When sending from both features, the system will instantly show you the available entries to choose from as soon as you begin to input a name or number from the Phonebook. When you receive messages, the system will match the caller’s information to the name you have configured in the Phonebook.

SIP stands for Session Initiation Protocol. This is the standard protocol used by the telecom industry to transmit voice communications, as well as multimedia elements (data, images, text messaging, etc.), over networks and the Internet. In addition to voice, SIP can be used for videoconferencing, instant messaging, media distribution and other applications.

Standard 911 emergency services send the user’s information through traditional landlines directly to the nearest emergency response centre. Enhanced 911 or E911 service allows mobile phones to dial 911 to automatically transmit the caller’s geographic position to emergency responders. With VoIP, however, 911 calls are forwarded to a third-party service provider that is required to automatically or manually route 911 calls to emergency response centres. Therefore, it is vital for VoIP telephony users to keep their phone system’s location information up to date with their VoIP provider at all times. Because it works with an Internet connection, your phone number is not automatically linked to your new address when you move to another location.

DID numbers are exclusively designed for receiving calls. When you place outgoing calls with our service, you are calling from your account rather than from your DID number, and the number you will pass on as your caller ID will be the one that is configured in your account settings on the Customer Portal.

VoIPXtreme does offer Local Number Portability (LNP) service, and your number may be available for porting. Please contact Customer Service to find out whether your current number is portable to the VoIPXtreme network, or if you already have an open account, please refer to the “Porting a Number” section of the guide at Porting a Number.

We strongly advise against this, as it may cause conflicts while routing calls to your device, as well as registration-related issues. If you need to register more than one device, please create and use sub-accounts to get new credentials for any additional device. For more information about sub-accounts, please check the related article on this subject, "Sub Accounts".

Since we are a BYOD service provider, all software and/or hardware installation needs to be performed by the customer. However, we do offer technical support via live chat and a ticket system (email) to assist users with the installation and configuration of their phones systems.Additionally, we provide detailed step-by-step configuration guides and samples on our wiki page at Configuration Samples.

We currently offer Virtual PRIs only for inbound traffic while outbound remains billed at a per-minute rate. However, there are no charges for increasing the amount of channels required to fulfill your outbound traffic demand. Simply reach out to our support or sales team.

Basically, any device or system that supports the SIP or IAX2 protocol will work with our service. If you bring your device (ATA, IP phone) from a previous provider, make sure that it is unlocked and that you are able to make changes to its configuration.

You can find configuration samples for most of the common devices and phone systems used with VoIPXtreme here: Devices If your device or system is not listed there but supports the protocol SIP or IAX2 and at least one of the following codecs: G711u, G729a or GSM, you should be able to use it, and you can always contact our Technical Support staff for additional assistance.

By default, your main account SIP password is the same as your Customer Portal password. If you have not changed your SIP password, it is the same password you use to log into the Customer Portal. You can change your SIP password on the Customer Portal at any time from the Main Menu, Account Settings page. Please check our related article for more information: General Security.

Usually, in order to receive better results, you should choose the server physically closest to your location. You can also send a ping to any of the servers to check the best response time. Please check our related article for more information about this subject: Choosing Server.

SIP communications can be encrypted with TLS-SRTP if your device supports it.

The maximum length a voicemail message is three minutes.

As a general rule, the vast majority of SIP software is compatible with VoIPXtreme. This software can be downloaded from the respective store or company website, depending on the OS (iOS App Store, Android Google Store, Windows Mobile, etc.). The same goes for software-based PBX Systems (asterisk for example) that accept SIP custom configurations.

With bursting, the Virtual PRI will have a reserve of channels that will remain inactive unless the PRI reaches its default inbound channels capacity. In an event where the regular channels of a PRI are maxed out, these dormant channels will activate in order to avoid the callers to reach a congestion or busy tone. These channels do not have any monthly fees tied to it, but instead they are charged on a daily basis only if they become activated and only the amount of channels that were used.For example, if your PRI has 5 additional channels in the bursting reserve but you only require to use 1 channel out of those 5, you will only be charged for that extra channel only for the day it was used.

On top of being highly flexible, there is no required equipment to have a virtual PRI configured with our service. Everything is managed directly from our system and you can request any change in the configuration to our team to match your needs.

The cost varies depending on the services used. For outbound calls, the cost is subject to the per-minute rate for the destination called and the billing increment. For inbound calls, the cost is subject to the rate plan of your phone number (DID), the monthly fee and the billing increment, if applicable. There may be additional monthly fees or setup fees, depending on the services to which you are subscribed. For more details about the cost of the service, visit the following link: Service Costs.

We do not charge any cancellation fee of any kind, you are free to cancel your account or number at any time you wish to.

Yes. VoIPXtreme allows you to change the billing plan of your US and Canadian DID number(s) whenever you wish. The plan can be changed on the Customer Portal without needing to contact technical support.

With VoIPXtreme, there are no “local” or “long-distance” calls. Each outgoing call is charged according to the per-minute termination rate for the destination called. Due to the advantages of VoIP technology, the rate for calling any given number will always be the same, no matter where you are when you place the call.

VoIPXtreme provides all the necessary tools to calculate expenses with no room for error. It is also important to remember that inbound and outbound calls are billed separately. For example, the cost of the flat-rate plan for a US-based DID number could be $4.25 a month and $0.00 per minute for inbound calls, whereas all outbound calls will still be charged as per the termination rates. For example, calling a US48 number is $0.01 per minute.VoIPXtreme works as a prepaid service provider, and you must deposit a minimum of $10 with a minimum threshold of $5 in your account to be able to send and receive calls.

Before receiving incoming calls, you need to order a DID from our stock by accessing your Customer Portal. You can also port a number that you previously had with another provider. For numbers in the United States and Canada, we offer two types of plans: a monthly flat rate or per-minute rate. As for outgoing calls, our billing is on a per-minute basis and, like any long-distance phone plan, the cost depends on the destination. You can access our detailed per-minute rates for different countries at Rates.

At VoIPXtreme, we charge for calls based on six-second increments. This applies for all countries except Mexico, where a sixty-second increment applies. A billing increment is a unit of measurement of call duration expressed in seconds. One minute is divided into ten periods of six seconds each. For a rate of $0.50 USD per minute, the user will be charged $0.05 USD per each six-second period. In other words, $0.05 USD x 10 six-second periods per minute = $0.50 USD per minute.

The billing of your toll-free number depends on the country in which your number is based (the United States or Canada). For a US / Canada toll-free number, there is a monthly charge of $2.99 and a rate of $0.030 per minute for inbound calls. For a Canadian only toll-free number, there is a monthly charge of $2.99 and a rate of $0.030 per minute for inbound calls.


There is a one-time setup fee of $2 for activation of the E911 service and a monthly regulatory fee of $2.00 per activated DID number. if you decide not to take the monthly 911 service and if there is a call for 911 it will be charged at $10/call for each 911 dialed without a plan.


The Virtual Fax feature is used for sending and receiving faxes (facsimiles) with the VoIPXtreme service, using a dedicated DID fax number. A DID fax number can be acquired on the Customer Portal in the Fax Numbers section under the Order DID(s) option from the DID Numbers menu. Regular DID voice numbers are not compatible with the Virtual Fax feature. In order to use our Virtual Fax feature, you will need to purchase a Virtual Fax DID number from our list of numbers. A DID fax number has a monthly fee of $1.99 with a per-minute fee of $0.029.

As they are different routes, Premium and Value routes offer different qualities of service and different rates. For example, the Canadian Value route offers some of the greatest rates on the market: the rate for outbound calls is $0.0052 per minute for most of Canada. This is a very good option if you are looking for the best wholesale rate to pay or to offer in case you are a reseller, while keeping a very good level of quality and reliability. As for the Canada/US48 Premium route, you pay flat rate of $0.01 (1¢) per minute for all of Canada and the continental USA. VoIPXtreme uses Tier-1 termination carriers for this route. While this route has a higher per-minute rate, you enjoy the same level of quality and reliability on every call. It is important to note that while the Canadian Value route usually delivers good results, the Premium route will consistently provide great results. As for international calls, VoIPXtreme also offers Value and Premium options. In this case, there is no specific rate; different countries will have different termination rates. In some cases, you will find the Premium route less expensive than the Value route.

No, we do not send paper invoices. You can consult your invoice online at any time by logging into our Customer Portal and going to Finances > Generate Invoice, where you can access the charges and all account activities for the billing period.

There are different types of DID numbers. They are mostly differentiated by their geographic presence.The types of DID numbers most commonly used by our customers include: Local DIDs from the United States or Canada International DIDs Toll-free numbers For more information about getting a DID number and other types of DID numbers, please see our related article Order a DID Number

Caller ID is a telephone feature that transmits a caller’s phone number to the call recipient’s phone. Where available, the caller ID number can be supplemented with the caller’s name (e.g., John Smith). There are two types of caller ID: caller ID number (CID) and caller ID name (CNAM). The caller’s phone number and subscriber information may vary depending on the location and the information on record with the carrier.

CNAM stands for caller ID name, which is the information that will be displayed on the call recipient’s phone when you place an outgoing call. If you will be making calls to Canadian numbers, you can simply pass the caller ID name from your device or system, as most of them support this. For calls to the United States, the caller ID name works differently. In this case, it is controlled by a national CNAM database with records of numbers and names matching each number. We can update the CNAM database upon request. For more information, please see our related article at Caller ID Name.

We don’t provide any hardware or software for using the service. This is a BYOD (“bring your own device”) service, which means that you are free to purchase the IP phone that best suits your particular needs. This is in contrast to providers that require their customers to purchase specific phone models to match their technology or even to purchase phones from them directly. You can get any type of IP phone from any communications specialty store. We also support all SIP-compatible devices.

Due to the nature of troubleshooting, which can prove time-consuming, we have opted to provide support via a ticket system (email) and live chat. At this point, technical support is not available over the phone.

We offer E911 service only for US and Canadian DID numbers (including US and Canadian toll-free numbers). This feature can be activated directly in the Customer Portal by accessing the E911 page from the DID numbers menu. More information is available in our related wiki article here E911.

We do not offer a calling card feature at this time. However, you can set up a calling card solution using your own system and our DID numbers, as long as the corresponding DID numbers are under our per-minute rate plan. You can also use our DISA feature, which allows you to set a number for our system to call, in order to receive a dial tone and place outgoing calls through the VoIPXtreme network. Just like a calling card, this feature is useful if you want to make a long-distance call from outside your calling area or if you don’t have a VoIP device readily available. For more information, see DISA.

We offer a virtual fax feature This feature can be used with special DID fax numbers, which can be acquired and configured through our Fax Portal for customers in the United States and Canada. It is also possible to port a VoIPXtreme DID voice number or a number from another provider into our virtual fax service. To port a number from another provider, simply go to the DID Portability section of our Customer Portal. For VoIPXtreme numbers, you can request an internal port by emailing our LNP department at Ports VoIPXtreme. The porting fee is $15 per number for both options. Note: This service can only be used to send faxes within the United States and Canada at this time. We cannot guarantee that international faxes will be properly received. Virtual DID fax numbers cannot receive regular voice calls or SMS messages—only faxes. Please see our related article for further details: Virtual Fax.

We do offer SMS service. SMS is available for a great number of DIDs and cities across the United States and Canada. The SMS service is available through the customer portal and also via SIP protocol from a supporting device or software. You can read more details about this feature in our related article SMS.

We do provide audioconferencing for our customers with a dashboard to manage and record the conference.

Our main offices are located in Montreal, QC, Canada. We also have a technical site located in Merida, Yucatan, Mexico, for the Latin American market.

The referral program allows you to receive VoIPXtreme credits for every friend you refer. The more referrals you make, the more credits you make. In order to get your credit, your friend has to open an account, deposit funds, make their first phone call and funds will be automatically added to your balance.

Yes. With the Ring Group feature, you can have incoming calls redirected to multiple destinations included in your Ring Group, where a member of the group is able to answer. When a call is placed with a DID number routed to a Ring Group, all members of that group will ring at the same time until the call is answered by one of them. You can add various types of members to a Ring Group: Main Account, Sub-Accounts, SIP URIs, Call Forwarding. You can also select which voicemail should be used by the system in case none of the members answer the call. The maximum number of members in a Ring Group is twelve: up to eight SIP, IAX2 or SIP URI members and up to four call forwarding entries per each Ring Group.

Due to the nature of the VoIP technology, a VoIP phone is capable of working just like a regular phone and even more, which means that you can place a call anywhere around the world on any mobile device(e.g., laptop computer, cell phone or tablet) carrying your same number at a much lower rate than youwould pay if calling from a regular landline. Furthermore, you use the same dialing format as you would from a regular phone to make calls. One of the great advantages of VoIP technology is that it enables free calls in many different ways by making use of each provider’s internal network capabilities. You can access the VoIP Customer Portal to check rates for incoming and outgoing calls for Canada, the United States and international destinations. You can choose between a flat monthly price or a per-minute rate plan for incoming DID numbers.

For your basic equipment, you need an IP phone or softphone or any other phone equipped with an ATA adapter. Since VoIP technology works with over the Internet, you will also need a high-speed Internet connection. If you wish to set up a company system, you will require other devices such as an Internet Protocol Private Branch Exchange (IP PBX), several lines, several routers, Virtual PRI and a PBX server. If you are using a softphone, you will need a VoIP headset and a computer or smartphone to make it work.

Yes. In the United States, all inbound calls will display caller ID with name (also known as CNAM), as long as the caller’s name has been added to the number on record in the CNAM database, and provided the call recipient’s DID number has the “Caller ID Name Lookup” setting enabled. In Canada, CNAM works as long as a valid caller ID name is being transmitted from the caller’s phone system. **It is important to note that while CNAM works with calls inside the United States and Canada, it will not work for international numbers.

Yes, we do support sub-accounts. Sub-accounts make it easy for you to share your VoIPXtreme account and make it more versatile. With sub-accounts, you can use multiple devices on your account.

Yes. VoIP offers a vast range of telephone numbers in many different area codes. Simply access the Customer Portal to see a list of available numbers. This solution is often preferred by customers who wish to make calls to or receive calls from customers, friends or family members living in different cities without incurring long-distance charges or for businesses that wish to have a local presence in many cities.

No. At the moment, we do not support emergency 911 dialing outside of the United States and Canada. We recommend using a traditional landline or your mobile phone to make emergency calls when you travel abroad.

At VoIPXtreme, forwarded calls are billed according to two different segments: inbound and outbound. When you forward your calls to a number, the inbound segment of the call is charged according to the billing plan you selected for your DID number (per-minute or flat rate), and the outbound segment of the call is charged according to our per-minute rates for termination, depending on the destination of the call, for the same duration as the inbound segment.

Call queues are specifically designed to manage incoming calls. By setting up a call queue, you can have many callers wait on the line until an agent is available to take their call. If you configure an IVR for your DID number, you can make it so that callers first hear a welcome message and interact with a voice menu before being sent to the call queue. At VoIPXtreme, the Call Queue feature allow users to customize their call queues to play pre-recorded messages about their company, music or advertisements for callers while they are on hold. Various ring strategies can be established to determine routing patterns for each call queue, such as Ring All (ring all available agents), Round Robin (distributes calls as evenly as possible), Least Recent (sends the call to the agent who least recently received a call), Fewest Calls (routes to the agent who has taken the fewest total calls in the session) and Random (leave it up to chance).

A sub-account, also referred to as extension, allows you to register more than one device to your main account to make or receive calls simultaneously. You can also use it as an internal extension for your office or even your house. Many of the features within VoIPXtreme make use of sub-accounts. Each sub-account, or extension, is assigned a unique user ID and password, which are required to register their dedicated VoIP device or devices.

Toll-free numbers are special numbers that are designed to allow callers to reach certain numbers (often long-distance) without having to pay long-distance charges. These numbers are mostly used by companies who wish to allow their customers to call them for free no matter where they are located. There are several toll-free area codes, namely 800, 888, 877, 866, 855, 844 and 833. They all work the same way, but the choice of prefix depends on the businesses advertising strategy. Traditionally, 800 numbers have been used for television and radio advertisements, but other prefixes like 888, 866 and 855 are gaining popularity.

Virtual SIP numbers are similar to standard DID numbers. The major difference is that virtual SIP numbers are not accessible via “PSTN”. They can only be reached via “SIP URI” over the Internet. For example, if you have a DID number with another provider that supports SIP URI forwarding, you could forward your number to a virtual number at VoIPXtreme, just as if it were one of our numbers.

SIP phones, also referred to as VoIP phones or softphones, allow users to make phone calls over IP or traditional networks using VoIP. SIP phones can be software-based (where software applications are installed onto your desktop or laptop to make phone calls over the Internet) or hardware-based (where the phone works just like a traditional one, except that it makes phone calls over an IP network instead of PSTN lines).

Call Forwarding allows users to redirect incoming calls to another phone number or to a mobile device such as a cell phone, tablet or computer. Calls can be forwarded to any number around the world. With call forwarding, you can program your phone, Customer Portal or VoIP software to automatically forward calls to your preferred mobile device (cell phone, laptop, softphone, etc.) or to any number capable of accepting calls.

With this feature, you can set a number for our system to call back in order to receive a dial tone and place outgoing calls through the VoIPXtreme network. This is useful if you want to make a long-distance call from outside of your calling area or if you don’t have a VoIP device readily available. When a DID is set up with the Callback feature, calls that are placed to this DID return a busy signal, and the system calls back the specified number and provides the user with a dial tone to place an outgoing call.

Caller ID Filtering allows you to filter incoming calls based on their origin (such as private, anonymous or unknown numbers or area codes). For example, if you receive unwanted calls from a telemarketer or survey company, you can set up a filter for each of your DIDs to route those calls to voicemail, play a pre-recorded message or simply disconnect the call. On the other end of the spectrum, you can give preferential treatment to your favourite customers and route their calls to provide them with a fully customized experience.

The DISA (Direct Inward System Access) is a feature that, when configured with a DID, will allow inbound callers to access outbound call service through your VoIPXtreme account, similar to what a calling card service does. When you call, you will be prompted for a PIN number and the telephone number you wish to reach.

IVR (Interactive Voice Response) is a telephone technology that works just like a virtual receptionist. With this technology, inbound callers interact with a voice menu using their telephone keypad or by speech recognition in order to be connected with the proper person, extension or department. This allows customers to get the information they need without having to wait to speak with an agent.

Latency refers to the speed with which data travels over the Internet and through network connections to reach your hosted VoIP service provider. Latency and bandwidth are the two main factors that determine your network connection speed. When transmitting sound, latency can cause static, dropped calls and choppy audio.

Packet loss is defined as the failure of transmitting and receiving data (audio, video, computer). It often occurs when an Internet connection becomes overloaded with data or traffic. Packet loss should always be zero when your phones are in use, in order to avoid poor sound quality or echo or jitter when transmitting images. Packet loss can be caused by hardware or software problems, including cabling, but the main culprit is usually insufficient capacity of the network being used.

PBX means Private Branch Exchange. Basically, it is a telephone exchange system that manages a company’s incoming and outgoing calls and manages internal communications between employees. The advantage of a PBX is that you can equip your system with more phones than physical phone lines. It also provides a vast range of features such as call waiting, voicemail, three-way calling, call forwarding and other, more advanced features such as call queues and interactive voice menus. As for IP PBX, it is a software-based PBX phone system solution that allows remote or mobile employees to connect to the company phone system or voicemail, no matter where they are, as long as there is an Internet connection.

The Phonebook feature allows you to configure up to 500 Phonebook entries with caller ID name (CNAM) overrides and up to 99 speed-dial codes for those entries. For example, you can create a four-digit Phonebook entry to call your favourite customers or relatives. Additionally, you can use a caller ID name (CNAM) override to identify inbound calls from important customers, regardless of whether their number is registered to a proper CNAM central database. Phonebook entries are also available with our Virtual Fax and SMS features. When sending from both features, the system will instantly show you the available entries to choose from as soon as you begin to input a name or number from the Phonebook. When you receive messages, the system will match the caller’s information to the name you have configured in the Phonebook.

SIP stands for Session Initiation Protocol. This is the standard protocol used by the telecom industry to transmit voice communications, as well as multimedia elements (data, images, text messaging, etc.), over networks and the Internet. In addition to voice, SIP can be used for videoconferencing, instant messaging, media distribution and other applications.

Standard 911 emergency services send the user’s information through traditional landlines directly to the nearest emergency response centre. Enhanced 911 or E911 service allows mobile phones to dial 911 to automatically transmit the caller’s geographic position to emergency responders. With VoIP, however, 911 calls are forwarded to a third-party service provider that is required to automatically or manually route 911 calls to emergency response centres. Therefore, it is vital for VoIP telephony users to keep their phone system’s location information up to date with their VoIP provider at all times. Because it works with an Internet connection, your phone number is not automatically linked to your new address when you move to another location.

Support

DID numbers are exclusively designed for receiving calls. When you place outgoing calls with our service, you are calling from your account rather than from your DID number, and the number you will pass on as your caller ID will be the one that is configured in your account settings on the Customer Portal.

VoIPXtreme does offer Local Number Portability (LNP) service, and your number may be available for porting. Please contact Customer Service to find out whether your current number is portable to the VoIPXtreme network, or if you already have an open account, please refer to the “Porting a Number” section of the guide at Porting a Number.

We strongly advise against this, as it may cause conflicts while routing calls to your device, as well as registration-related issues. If you need to register more than one device, please create and use sub-accounts to get new credentials for any additional device. For more information about sub-accounts, please check the related article on this subject, "Sub Accounts".

Technical

Basically, any device or system that supports the SIP or IAX2 protocol will work with our service. If you bring your device (ATA, IP phone) from a previous provider, make sure that it is unlocked and that you are able to make changes to its configuration.

You can find configuration samples for most of the common devices and phone systems used with VoIPXtreme here: Devices If your device or system is not listed there but supports the protocol SIP or IAX2 and at least one of the following codecs: G711u, G729a or GSM, you should be able to use it, and you can always contact our Technical Support staff for additional assistance.

By default, your main account SIP password is the same as your Customer Portal password. If you have not changed your SIP password, it is the same password you use to log into the Customer Portal. You can change your SIP password on the Customer Portal at any time from the Main Menu, Account Settings page. Please check our related article for more information: General Security.

Usually, in order to receive better results, you should choose the server physically closest to your location. You can also send a ping to any of the servers to check the best response time. Please check our related article for more information about this subject: Choosing Server.

SIP communications can be encrypted with TLS-SRTP if your device supports it.

The maximum length a voicemail message is three minutes.

As a general rule, the vast majority of SIP software is compatible with VoIPXtreme. This software can be downloaded from the respective store or company website, depending on the OS (iOS App Store, Android Google Store, Windows Mobile, etc.). The same goes for software-based PBX Systems (asterisk for example) that accept SIP custom configurations.

With bursting, the Virtual PRI will have a reserve of channels that will remain inactive unless the PRI reaches its default inbound channels capacity. In an event where the regular channels of a PRI are maxed out, these dormant channels will activate in order to avoid the callers to reach a congestion or busy tone. These channels do not have any monthly fees tied to it, but instead they are charged on a daily basis only if they become activated and only the amount of channels that were used.For example, if your PRI has 5 additional channels in the bursting reserve but you only require to use 1 channel out of those 5, you will only be charged for that extra channel only for the day it was used.

On top of being highly flexible, there is no required equipment to have a virtual PRI configured with our service. Everything is managed directly from our system and you can request any change in the configuration to our team to match your needs.
