SIP trunk (Session Initiation Protocol trunk) connects a PBX system to the PSTN (Public Switched Telephone Network) via the internet, replacing traditional phone lines and enabling VoIP calls for lower cost and more flexibility. It acts as a digital bridge between your phone system and the global telephone network.
PBX is a SIP trunk provider that enables internet-based calls. With a PBX.IM account, you can use VoIP services in a setup that’s scalable and affordable.
Expand your voice capacity instantly. Connect your PBX to reliable SIP trunking in the countries you operate and scale globally with ease.
