Umm, yeah. I knew all that :-)

Since the OP is using ReceiveFAX in his dialplan, that means Asterisk
sent the T.38 re-INVITE. Under the assumption that's he posted the
snippets from corresponding sections of successful and failed calls, the
SDP parsing output we saw would be from the response to the re-INVITE.
In the second example, the response to the re-INVITE did not include a
T.38 media stream.

I agree, though, that a more complete log would be most helpful in
clarifying the situation.
