[Serusers] Incorrect invite from PDT module?

[Dave Bath]

Hi guys,

Im having a small problem with the PDT module.  It seems to be installed
with the database set up correctly, and it seems to translate the codes
correctly.  However, when a call is placed using the PDT module, the
invite appears to be incomplete (at least, as reported by acc module),
and reports:

ACC: transaction answered: method=INVITE,
i-uri=sip:839503018 at sip.dev.inmarsat.com, o-uri=sip:3018 at sip.prodec.tv

Eventually, SER gets a timeout.  

I was wondering two things - does it look like this is indeed a
malformed invite or is that that my ser.cfg for some reason isn't
responding correctly to the reply from the forwarded domain?

Incidentally, if I dial the external address directly from the telephone
keypad, all is fine and I see the following in the syslog.

ACC: transaction answered: method=INVITE, i-uri=sip:3018 at sip.prodec.tv,
o-uri=sip:3018 at sip.prodec.tv,
call_id=62C50F87-E5D1-4F8B-B0BD-5A1146A4A812 at 161.30.94.150, from=Dave
Bath <sip:admin at sip.dev.inmarsat.com>;tag=2642545628, code=200

If anyone has any ideas, I have posted the ngreps underneath.  If you
want to take a look at the ser.cfg, then please just let me know.

Thanks very much in advance,

Dave
