Hello list.

I’m using the sample configuration that comes with Kamailio RC3.  (version: kamailio 3.0.0-rc3 (i386/linux)).

I have two IP phones registered in the proxy.  If I call from one to another and the call is cancelled a “500 Server Internal Error”  message is send back to the caller (please see the debug attached) by the proxy.

This is not happening with Kamailio 1.4 or Opensips 1.6 (using the sample configurations).

Could be some problem?
