How Does SIP Trunking Work?

Session Initiation Protocol (SIP) sends voice, video, and unified communications via digital packets over an internet connection through SIP trunks.

A SIP trunk can hold multiple SIP channels. Each channel is equal to one inbound or outbound call. SIP trunking allows you to have multiple SIP channels. This way, you can make and answer multiple calls at a time through just one SIP trunk.

SIP can easily be integrated into your existing phone system or IP-enabled PBX system.
