    SIP Trunking FAQs

    sip-trunking-info-card

    What is SIP Trunking?

    SIP trunking (Session Initiation Protocol trunking) 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.IM is a SIP trunk provider that enables internet-based calls. With a PBX.IM account, you can use VoIP services without costly hardware and a scalable, affordable setup.

    Our SIP trunk connections support TLS (Transport Layer Security) and DTLS (Datagram Transport Layer Security) encryption, making it virtually impossible for unauthorized parties to eavesdrop on your calls.
