How SIP Trunks work

SIP trunks are digital VoIP “lines” that significantly reduce call charges for businesses of any size whilst allowing complex routing options to maximise the efficiency of your phone system. For example, a US-based company might add some of our SIP trunk channels to their PBX to route all UK-bound calls through. Adding a SIP trunk route to your existing cloud-based or inhouse PBX system is really easy within your software (eg 3CX or Asterix).
