Sip Trunking


What is sip trunk?

A SIP Trunk is the virtual link between your PBX and the PSTN over the internet. It allows you to make outbound calls and receive inbound calls using an IP connection (VoIP) rather than a traditional ISDN/PSTN line. With ISDN/PSTN being phased out and moving to all-IP, SIP Trunks will be essential.
