Session Initiation Protocol (SIP) Phone Systems in Toronto
There is a lot of misinformation out there regarding Session Initiation Protocol (SIP) business phone systems. Many people do not have a clear understanding of what it is and how it works. If you have heard of the term SIP trunking and are wondering why so many businesses are switching out their traditional telephone lines for services that use public Internet, here’s what you need to know about SIP systems and how they can benefit you.
What Is a SIP Phone System?
A Session Initiation Protocol (SIP) phone system, by definition, is a communications protocol for controlling and signalling multimedia communications sessions through the use of Internet telephony for audio and video calls, Internet Protocol (IP) telephone systems, and instant messaging over IP networks. The term SIP trunking is a related word, and it is defined as a process that makes it possible for businesses to communicate using telephone services over the public Internet or private circuits, instead of using traditional analog telephone lines or Primary Rate Interface (PRI) circuits. SIP trunking is provided for businesses by carriers, including but not limited to, Rogers, Bell Canada, and Primus.
Features of SIP
SIP sessions include different types of multimedia such as Internet telephony calls, video conferencing, and other forms of unified communications. Participants can be invited to unicast or multicast sessions that either do or do not involve the initiator. It is important to understand that SIP on its own does not provide communication services, but its features can be used to facilitate various services. These features are known as “primitives,” which allow extra information to be put into a SIP message. For example, a user’s photo can be linked to directory information to create a media-rich caller ID. When establishing and terminating multimedia sessions, the SIP communications protocol determines the following five attributes:
How Does It Work?
SIP systems can be used externally over the public Internet or managed circuits, or internally within the phone system itself. It works as part of a Voice over IP (VoIP) system to make and receive telephone calls, conference calls, video calls, etc. Some SIP trunk providers can bundle long-distance charges in their monthly fee, meaning businesses like yours can save money in the long run. SIP trunks are generally more affordable than traditional copper analog lines and PRI digital lines, and they can be delivered to the business via fibre, coaxial cable, or even DSL. Bandwidth is extremely important for this system to run smoothly, and the voice quality on the SIP trunks is dependent upon bandwidth and QoS (Quality of Service), which can be used to prioritize voice streams over data streams.
