SIP Trunks

Session Initiation Protocol

Sip Trunks is a technology used for establishing a voice communication session on a data network (for example over the Internet). A SIP Trunk provides the same service you get from a traditional analog phone line.The difference is, instead of being a physical wire, a SIP Trunk is a “virtual” phone line which is provided by a SIP trunk provider. They use your data circuit (T1, Cable Modem, DSL, Ethernet over Copper, etc) to connect your phone system back to their network.
