Re: SIP Ext GW problem

Yes I did both ways. Via ippstat menu/option 15
and with the command ippstat telnet d XXX t 1440
but neither work...so cannot enable mirror
However I managed to get outbound working fine. Incoming still has 1 way speech but working on it now
Outbound problem was:
I had: Outbound Calls 100 REL + Supported on my external Gateway as that was a request from them in original spec document.
So when call is established I have following happening:
Invite
100 trying
183 session description from them
PRACK from me
401 from them
183 from them
183 from them
183 from them
Cancel from me
200 ok from them
487 request terminated from them
ACK from me
Problem was in their 183 Session progress they send "Require: 100rel
The PABX then responds with a PRACK (As they asked for it in the Progress message)
Then they send 401 Unauthorized, and keep on sending 183 messages after that but pabx does not respond witk ACK as it was not authorized and then the call cuts.
So I disabled the PRACK feature on SIP trunk and call works fine.
(This morning when I checked new traces I saw they removed the Required: Rel100 request from their Session Progress in the night.
)
Problem was on their side as OXE reacted exactly the way they requested but then they send 401.
