Fax Over IP Gateway Protocols SIP – T.38 – SoftModem

ITU-T T.38 recommendation specifies the communication protocol to be used between facsimile gateways or between facsimile gateways and IAF ( Aware device) connected via an Internet network in order to transfer fax between G3FEs (Group 3 Fax Equipments) connected to facsimile gateways via PSTN (Public Switched Telephone Network) or between G3FEs and IAFs.
