Guy,

Thanks for the bug fix.

>From what I know about T38, the call is always setup as a voice call.  When
the terminating device detects the CED tone from the fax machine, it
initiates the switch over to T38 by sending an H245 RequestMode towards the
originator.

I've checked in a fix.

...which explains why, although the code was crashing in the "set up an 
RTP conversation" code, no RTP traffic appeared - the T.38 call was 
going over TCP, but the "set up an RTP conversation' code was assuming UDP.

Is there anything in that capture that indicates that it's setting up a 
T.38 call, rather than an RTP call?  Presumably we shouldn't just be 
assuming that H.245 is setting up an RTP session.
