SIP Trunking

What is SIP Trunking?

Session Initiation Protocol (SIP) trunking is a technology that allows businesses to use the internet to make and receive phone calls instead of traditional phone lines. It enables voice and data traffic to travel over the same connection, which simplifies communication networks and lowers costs. SIP trunks are virtual phone Number lines that run over a data connection, allowing businesses to add phone lines and adjust call capacity on demand.

How SIP Trunking Works?

SIP handles call setup and teardown between endpoints. Calls are broken into IP packets routed over the network between the business PBX and SIP provider. Dedicated SIP trunks or shared MPLS networks are used for connectivity. The provider handles PSTN interconnection.
