What is SIP trunking?

Voice Over IP (VoIP) is used in Session Initiation Protocol (SIP) trunking to facilitate the connection between an enterprise Private Branch Exchange or PBX to the Internet.

SIP is a standard for initiating multimedia sessions and trunking is the process of connecting several nodes in a communication system that can carry many signals at a time.
