SIP Trunking

Session Initiation Protocol (SIP) is a standards-based protocol used to initiate and terminate various forms of communication, including  Voice Over IP (VOIP) phone system equipment, Instant Messaging, voice, and video conferencing.

It is becoming increasingly popular for companies to replace traditional telephone carrier services (PRI and analog services) with VoIP telephone services delivered over IP-based connections using the SIP protocol. These SIP services are being provided by Internet Telephony Service Providers (ITSP). With every other form of corporate communication being delivered via the Internet Protocol (IP), doesn’t it make sense that corporate dial tone converge over IP as well? It’s a natural progression.
