babyTEL T.38 SIP Trunking

Save Time and Money by Using a True, Internet-Only Fax Solution

What is T.38 SIP Trunking?


SIP (Session Initiation Protocol) T.38 (real-time fax transmission) Trunks are “virtual lines” that allow users to send and receive faxes via the internet in real time. SIP trunking creates a path via the Internet for a single fax call between your PBX phone system and the legacy worldwide Public Switched Telephone Network (PSTN). Instead of a physical trunk of wires for PSTN lines, SIP trunking provides a virtual trunk over the internet to PSTN lines. A single internet connection to your PBX phone system can carry hundreds of SIP trunks depending on needs.
