Summary:                    1.4 does not send any SIP messages after the "100
Trying" to the T.38 INVITE requesting side
Description: 

Asterisk 1.4 does not send any SIP messages after the "100 Trying" to the
T.38 INVITE requesting side. chan_sip talk to the B-side, where itself send

With 1.6 and trunk chan_sip is talking to A-side.

In the attached sip trace, you see the only answer to C.C.C.C is only the
100 Trying, then nothing.
