SIP Trunking and your business
SIP, an acronym for session initiation protocol is a signalling protocol, responsible for initiating, maintaining and ending multimedia sessions.
SIP Trunking enables you to connect your pre-existing IP PBX to your clients, operating over the IP network.
In fact, you can essentially think of it as a digital phone line replacing the traditional PSTN lines, allowing for both voice and video calls.
What is SIP Trunking?
While “SIP trunk” sounds like a technical term, the concept itself is rather simple:
“SIP” refers to Session Initiation Protocol, responsible for sending and receiving calls, and “trunk” simply refers to a connection between two points.
A SIP phone number isn’t attached to any physical location, therefore allows for simple rerouting to different geographic locations.
SIP channels can be added or removed quickly and easily, making them a very flexible choice for telecommunications.
SIP Trunking allows for the setup of a number of reliability measures including mobile failovers and hosting the SIP trunks across multiple servers.
