Hi Brian,

thank you for your fast response.
It is not a FreeSwitch problem!

I solved it in the meanwhile.
It was a firewall rule problem.
FreeSwitch was not able to reach the proxy server.
Strange fault, since I was able to make calls.

Problem is solved.

Thank you!

Pay close attention to the record route and path on the original request.  Do you have a full trace?

Hi,

we need a proxy (kamailio) in front of freeswitch.
In general it works, but ...
I get no BYE if the client direct connected to freeswitch hangs up.

The INVITE from the proxy contains the correct Record-Route entry:

INVITE sip:yyy@xxx.xxx.xx;transport=TCP SIP/2.0
Record-Route: <sip:proxy.address.xxx.xxx;transport=tcp;lr>
Via: SIP/2.0/TCP
proxy.address.xxx.xxx;branch=z9hG4bK4fcd.b5f0a67d3fa655e0f3b123a8e95ff5b5.0;i=2
Via: SIP/2.0/TCP
phone.address.xxx.xxx:53558;received=phone.address.xxx.xxx;rport=53558;branch=z9hG4bKPj30dd14b14974bcb42dc24d2f650f;alias

Any ideas?
