What is SIP Trunking?

SIP, or Session Initiation Protocol, is the standard communications protocol for the transmission of voice across a data network.

A SIP trunk replaces the need for traditional analog, T1-based Public Switched Telephone Network (PSTN) connections with termination instead provided over a company’s public or private Internet connection.
