Frequently asked questions

A VoIP works just like a regular phone, which means that you can place a call anywhere around the world on any mobile device (laptop computer, cell phone, tablet) at a much lower rate than you would 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 you can call any country in the world for free if the recipient also uses VoIP technology, no matter what device they use. You can access the VoIP Customer Portal to check rates for ingoing and outgoing calls for Canada, the US and international destinations. You can choose between a flat monthly price or rate-per-minute.
Our main offices are located in Montreal, QC, Canada. We als have a Technical Site located in Merida, Yucatan, Mexico for the south-american market.
There are different types of DID numbers. They are mostly differentiated by their geographic presence. Local DIDs from US or Canada. International DIDs. Toll Free numbers. These are the most common used by our customers. For further information about getting a DID number and other types please check our related article Order a DID Number.
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 updated at all times with their VoIP provider. Because it works with an Internet connection, your phone number is not automatically linked to your new address when you move to another location.
SIP stands for Session Initiation Protocol. It 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 video conferencing, instant messaging, media distribution and other applications.  
The Phone Book feature allows you to configure an unlimited amount of speed-dial entries and Caller ID name (CNAM) overrides. For example, you can create a 4-digit Phone Book entry to call your favorite customers or relatives. Additionally you can have a Caller ID name (CNAM) override to identify inbound from important customers whether or not their number is registered to a proper CNAM central database. Phone Book 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 when you start inputting either a number or a name from the Phone Book. When you receive messages, the system will match the caller’s information to the name you have configured in the Phone Book.
PBX means Private Branch Exchange. It basiacally is a telephone exchange system that manages a company’s incoming and outgoing calls and manages internal cmmunications 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.
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, otherwise they result in poor sound quality or echo or cause jitter when transmitting images. Packet loss can be caused by hardware or software problems including cabling, but most of the time, the main culprit is the insufficient capacity of the network being used.
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 choppy audio. When transmitting images, latency causes jitter, delayed or freezed images.
Interactive Voice Response or IVR is a telephone technology that works just like a virtual receptionist. With this technology Inbound callers are introduced to an interactive voice menu with which they can interact to digits on their telephone keypad to be directed to the proper person, extension or department. This allows customers to get the information they need without having to wait on line to speak to a an agaent. While most interactions involve choosing simple numbers, other options may require the caller to speak detailed information such as the name of the department or person they wish to be directed to indicate the query topic they are calling for.
Referred Direct Inward System Access ( DISA ) this feature works exacly like our CallBack feature. You can set a number to be called to by our system in order to receive a dial tone and place outgoing calls through Sora Telecom network. This is useful for those who wish to make a long distance call and are outside of their calling area or don't have a voip device readily available. When a DID is set up with the callback feature, calls thar are placed to this DID return a busy signal and the system calls back the specified number and present the user with a dial allows you to use our system for placing outgoing calls, even if you are not close to any device where you are registering your account or sub account.
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.
CNAM stands for CallerID Name and it's the information that will be displayed in the phone of the receiving party, 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. The Caller ID name on US calls works differently, this is controlled by a national CNAM database with records of numbers and names matching each number. We can update the CNAM database under request. For more information please check our related article at [Caller ID Name]
CallerID 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 telemarketing or survey company, you can setup a filter for each of your DID to route their calls to a voice mail, a pre-recorded message or simply have your system disconnect the call. On the positive side, you can give preferencial treatment to your favorite customers and route their calls to provide them with a fully customized experience.
Caller ID is a telephone feature that transmits a caller’s phone number to the recipient’s phone. Where available, the caller ID number can be supplemented with the name of the caller (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 according to their location and the information they have registered with their carrier.
With this feature, you can set a number to be called to by our system in order to receive a dial tone and place outgoing calls through Sora Telecom network. This is useful for those who wish to make a long distance call and are outside of their calling area or don't have a voip device readily available. When a DID is set up with the callback feature, calls thar are placed to this DID return a busy signal and the system calls back the specified number and present the user with a dial tone.
Call Forwarding allows users to redirect incoming call to another phone number or to a mobile device such as a cell phone, tablet or computer. Numbers 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.). 
Also referred to as VoIP Phones or Softphones, SIP phones allow users to make phone calls over IP or traditional networks using VoIP. Also known as VoIP phones, SIP phones allow users to add various functionalities such as web, email, chat to their basic phone capabilities. SIP phones can be software-based, which means that their software applications are installed onto your desktop or laptop to make phone calls over the internet or hardware SIP phones that work like traditional phones with the difference that they make phone calls through IP network instead of PSTN lines.
Also known as Follow-me or Find-me, virtual phone number is a secondary or additional phone number that is usually issued from other area codes outside of the user’sgeographical location. It is used mostly for forwarding calls to a pre-set primary number. Since virtual numbers are not attached to a specific device or hardware, they can also have their own voice mail, which is separate from the user’s primary number. Virtual numbers are especially effective for businesses who wish to have a local number in several different countries, since calls coming to their virtual phone number are automatically forwarded to their main office.
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 Sora Telecom 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.
Call queues are specifically designed to manage incoming calls. By setting up a calling queue, you can have many callers wait on the line until an agent is available to take their call. Callers first hear a welcome message and interact with an IVR menu before being sent tothe call queue. Most systems allow users to customize their call queues to play pre-recorded messages about their company, play music on hold, advertisements for on-hold callers. Various ring strategies can be established to determine routing patterns for each call queue such as ring all 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).

As for Incoming calls, you are billed according to your incoming plan.

Toll free numbers are special numbers that are designed to allow callers to reach certain numbers (often long-distance) without having to pay paying 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, 866, 888, 844 and 855. They all work the same way, but the choice of prefix depends on a businesses advertising strategy. Traditionally, 800 numbers have been used for television and radio advertisements but other prefixes like 888, 866, 855, are gaining more and more in popularity.

At Sora Telecom we charge calls based on a 6 seconds period increment. This applies for all countries except for Mexico where the 60 second increment applies. Here is a short explanation about how this works. Billing Increment is a call duration measurement unit expressed in seconds. 1 minute is divided into 10 periods of 6 seconds. Let's say there is a rate of $0.50 USD per minute, then the user will be charged for 5 cents per each period of 6 seconds. (0.05 USD )* (10 periods on a minute) = $0.50 USD per minute.
No, we do not sent paper invoices. You can consult your invoice on-line at any time by logging into our Customer Portal where you can access , charges and all account activities for the billing period.
Sora Telecom 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 DID number can be $4.95 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. Sora Telecom works as a prepaid service provider, and you need to deposit a minimum of $25 in your account to be able to send and receive calls.
The Billing Increment is a call duration measurement unit expressed in seconds. For example, with a $0.0100 per minute rate, and a 60 seconds billing increment, any call less than 60 seconds is rounded up to 60 seconds or 1 full minute of usage. A 5 seconds call and a 50 seconds call are both billed as 1 minute or $0.0100. With our 6 seconds billing increment, a 5 second call will be billed as 6 seconds or 1/10 of 1 minute or $0.0010. This way, you don't get charged for a whole minute just for a 10 seconds call.
As they are different routes, premium and value routes offer different qualities for the service and different rates. For example, Canada value route offers some of the greatest rates on the market, the outgoing call rate per minute is $0.0052 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 Canada and the continental USA. Sora Telecom uses Tier-1 termination carriers for this route. While this route might have a higher rate per minute, you enjoy the same level of quality and reliability on every call. It is important to note that while Canada Value usually delivers good results, Premium Route will consistently provide great results. As for international calls, Sora Telecom 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. Local DIDs from US or Canada. International DIDs. Toll Free numbers.

If you want to make ten calls at the same time, you should have a 1.5Mbit Internet connection in both directions. If you have a connection with 1.5Mbit down and 768Kbit up, you can only make five simultaneous calls, because the uplink speed is the limiting factor.
