Can you send an ngrep dump? I think the message details are important.

                    setflag(1);
                    consume_credentials();

    if(lookup("location")) {
                    # if found, forward there...
                    t_relay();

here you need an "exit;"

                    } else {
                    prefix("+");
                    rewritehost("ourpstngateway");
                    };
            };

Hi Brandon,

what is really strange is that you have the request forwarded 8.11.1.7 -> 216.120.224.163 and in the same time the proxy sends an error rely back 8.11.1.7 -> 216.120.224.171 which is totally bogus.

can you provide detailed logs (use debug 7) to trace the error which triggers the 500 reply?

regards, bogdan

Can someone explain what is happening here. On the dialing end @216.120.224.171 I get immediate congestion after the INVITE, on the receiving end @216.120.224.16 I get ringing even after I hang up. Relevant tethereal and openser.cfg below...
