Re: [Users] Cisco Gateway Disconnects the call

Thu, 13 Jul 2006 02:20:37 -0700 

Hi!

next time, please use the "-W byline" switch of ngrep.
The problem is the ACK - it is totally wrong - the request URI and the Route header is bad
If your client is RFC3261 complient, it should put the URI from the Contact of the 200 OK into the request URI, not the URI of the Record-Route header (this is the old SIP RFC behaviour).
Also if your client uses the old way (strict router), it has to put the complete Contact URI of the 200 Ok into the Route header. 

Which client are you use?

regards
klaus

Any idea what’s wrong?
