SIP is an abbreviation for Session Initiation Protocol. While many people are just learning about SIP, it was designed in 1996 by Mark Handley and his team. Later it received approval from the Internet Engineering Task Force (IETF). It is an IP standard established by the Internet Engineering Task Force. There are many protocols that can be used for VoIP, but SIP is the most common and widely used.
The acronym “SIP” stands for Session Initiation Protocol. SIP Trunk is a method of delivering telephone and other unified communications services over the internet. It works with a SIP enabled on premise or hosted PBX (private branch exchange). SIP Trunk replaces traditional telephone lines or PRIs (Primary Rate Interface). SIP defines the messages that are sent between endpoints and it governs establishment, termination and other essential elements of a call.
In short, SIP Trunk is a technology that allows businesses to make voice and multimedia calls over the internet instead of traditional phone lines.
Any business that requires cost-effective and scalable voice communication can benefit from SIP Trunk. It presents an excellent opportunity to achieve substantial cost reductions on local, long-distance, and international calls.
