What is a SIP Trunk?

A SIP Trunk provider provides you a line or (trunk) with the external world. So, when a call is made from an outside line to an internal line of the PBX, the call will use the specified SIP trunk as a path. If a client or tenant has issues with outbound or inbound calls, which is common, we recommend to check the functionality of the SIP trunk.
