What is SIP Trunking?

Session Initiation Protocol (SIP) Trunking replaces traditional analog phone lines (PRIs) with a virtual connection over the internet. It connects your on-premise or cloud-based Private Branch Exchange (PBX) to the Public Switched Telephone Network (PSTN), allowing you to make and receive global calls at a fraction of the cost.

Frequently Asked Questions

A standard uncompressed SIP call (G.711 codec) uses about 85-100 kbps of bandwidth in each direction. If you use a compressed codec (like G.729), it can use as little as 30 kbps per call.
