What Does SIP Trunking Do?
SIP Trunking is based on SIP. SIP stands for Session Initiation Protocol. SIP is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. It is widely used as the signaling protocol for VoIP calling and is widely thought of as the standard for VoIP calling.
Typically, a company’s VoIP calls will involve a circuit switched handoff to the PSTN outside of the company’s local area network. With SIP Trunking, the company’s VoIP Service Provider handoff’s calls via the Service Providers SIP Network. Calls that are going to the PSTN will routed over the Service Providers IP backbone to the nearest PSTN gateway.
For the truly non-technical, a SIP Trunk is similar to a phone-line, except that a SIP Trunk utilizes the IP network, not the PSTN. SIP Trunking also allows for convergence of voice and data onto common all-IP connections.
