[OpenSIPS-Users] ACK bug help needed

[Brian Southworth]

Hi Razvan,

 
I just checked my cfg.

 
It contains this: 

 
if (has_totag()) {

        if (topology_hiding_match()) {

            xlog("Succesfully matched this request to a topology hiding dialog. \n");

            xlog("Calller side callid is $ci \n");

            xlog("Callee side callid  is $TH_callee_callid \n");

            t_relay();

            exit;


        } else {

            if ( is_method("ACK") ) {

                if ( t_check_trans() ) {

                    t_relay();

                    exit;

                } else

                    exit;

            }

            sl_send_reply("404","Not here");

            exit;


        }

    }

Hi, Brian!

OpenSIPS doesn't need to send an ACK back, it has to relay the 200 OK to the caller, and the caller will send the ACK back. Can you confirm you are doing record_route() on the initial INVITE?
Also, can you post somewhere a SIP trace/pcap?

Best regards,

Hi All,

 
I seem to be having issues with outbound calls, the calls go out and the connection is established.

But when the asterisk gateway send the 200OK back from the provider to opensips proxy, the proxy doesn’t send the ACK packet back to asterisk it just keeps looping it to itself.

 
Any help would be appreciated.
