Hey Daniel,
 
Unfortunately, i do not maintain the system at 80.234.135.99.  However, i am not sure there is anything wrong with their system anyway....  as you see, i have attempted to dial from my UA once dialling a full address (in this case 3018 - at - sip.prodec.tv)  which was responded to correctly, and once by dialling 839503018 where 83950 should be translated as sip.prodec.tv using the PDT module. Hence, ser should finally send the invite to 3018 - at - sip.prodec.tv in the same was as if i dialled the full address manually, no? There should be no difference, once that invite request, has left ser (161.30.94.136) in how the remote system handles it.
 
As you can see from the syslog:
 
ACC: transaction answered: method=INVITE, i-uri=sip:839503018 at sip.dev.inmarsat.com, o-uri=sip:3018 at sip.prodec.tv

 
ACC: transaction answered: method=INVITE, i-uri=sip:3018 at sip.prodec.tv, o-uri=sip:3018 at sip.prodec.tv, call_id=9C912086-C197-484D-8AD2-E261F1A3234A@161.30.94.150, from=Dave Bath <sip:admin at sip.dev.inmarsat.com>;tag=2122510239, code=487
 
for some reason using the pdt module appears to issue a malformed invite request... unless soemthing in ser.cfg is not configured correctly.
 
Is my logic totally off? I appreciate your words of wisdom very much...
 
Dave

Hello,
I see that the request was forwarded from 161.30.94.136:5060 to
80.234.135.99:5060 and you get back a 100 trying. PDT does its job on
161.30.94.136, as far as I assume, so there should be a problem on the
other site 80.234.135.99, could you check that system too?
