What is SIP Trunking?

Session Initiation Protocol (SIP) trunking is the digital method of making and receiving phone calls and other digital communication over an internet connection.

SIP trunks not only carry voice calls, but it’s also used for multimedia communication that combines voice, video and messaging services.
