Max Datagram
In some cases,T.38 endpoints will provide a T38FaxMxDatagram value (during
T.38 setup) that is based on an incorrect interpretation of the T.38
recommendation, and result in failures because Asterisk does not believe it can
send T.38 packets of a reasonable size to that endpoint (Cisco media gateway
are one example of this situation).In these cases, during a T.38 call you will see
warring messages on The console/in the logs from the Asterisk UDPTL stack
complaining about lack of buffer space to send T.38FaxMaxDatagram value
specified by the other end[point, and use a configured value instead.
Fax Detect
FAX detection will cause the SIP channel to jump to the ‘faX’ extension (if exists)
based one or more events being detected. The events that can be detected are
an incoming CNG tone or an incoming T.38 re-INVITE request.
