The T.38 support in Asterisk 1.4 is only pass through. Asterisk is not
an endpoint or gateway of any sort. It only works passthrough in
SIP to SIP calls without chan_local or chan_agent involved.

Both endpoints of the call will need T.38 support and have T.38
enabled in sip.conf.

Asterisk 1.4 as I see it is still a bit unstable and not ready for
production use. Be careful out there.
