The T.38 Fax Support feature provides support for T.38 facsimile UDPTL (User Datagram Protocol Transport Layer) according to RFC 2833. The capability to send, receive, and process the signals to and from the gateway for tone detection and T.38 fax relay events is provided.
Support of the loose call agent controlled mechanism is provided, since it is not required to identify the support for T.38 at the start of the call.
An administration parameter is provided for trunk gateways and SIP endpoints to select the T.38 fax relay support capability.
