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@sip.dev.inmarsat.com, o-uri=sip:3018@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@sip.prodec.tv, o-uri=sip:3018@sip.prodec.tv, call_id=62C50F87-E5D1-4F8B-B0BD-5A1146A4A812@161.30.94.150, from=Dave Bath <sip:admin@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

---- Dialing Using pdt module …. Should the “to” field in the 3rd trace be sip:839503018@sip.dev.inmarsat.com or should it be 3018@sip.prodec.tv now?
