What is SIP trunking?

In simple terms, SIP trunking enables a PBX (Phone Exchange System) to send and receive calls via the internet and is able to control voice, video and messaging applications.

Essentially an internet phone line, each VoIP call requires one SIP trunk. A good quality broadband service can accommodate multiple SIP trunks. SIP trunks are much cheaper than traditional phone lines.
