SIP Trunking

SIP, or Session Initiation Protocol, is a protocol for signaling and controlling multimedia communication sessions in applications of Internet telephony for voice and video calls, in private IP telephone systems, as well as in instant messaging over Internet Protocol (IP) networks.

SIP Trunking uses VoIP to connect a PBX between the Internet and the Public Switched Telephone Network (PSTN), replacing a traditional "phone trunk" such as a Primary Rate Interface (PRI) or analog line. This solution requires an on-premise PBX and a gateway to connect your Internet telephony service provider to a PBX.

SIP Trunking allows customs to turn up voice services on the fly. Lines and Circuits are delivered in less than 3 to 5 weeks.
