Hello,

as I said in a previous email, you have to describe what match_dialog() and fix_route_dialog() do in order to be able to help you. It is very unlikely someone here has any knowledge of other sip servers apart of Kamailio, as you write to kamailio dev list.

If you don't know why are those function in your config and what they are supposed to do, then it is better to remove them anyhow.

As another guess to try helping:

- replace:

if (match_dialog()) {

- with:

 if(is_known_dlg()) {

Then remove completely:

                       if ($DLG_status==NULL) {
                                xlog("Dialog NULL");
                        }
                        else {
                                fix_route_dialog();
                        }

Test and see if it works as you need.

This is the last attempt to give you blind guidelines. If you want further assistance, you have to describe what you need to get as SIP routing. Nobody will spend time to read on internet for you and more important, if you don't know what is supposed to do in terms of SIP routing, then you are doing it all wrong.

I am saying it because in case you do a telephony service without properly understanding what you do with kamailio (or other voip system such as asterisk, freeswitch, ...), it will not last long until someone breaks your voip system, which can cost you a lot in damages.

                                remove_hf("Route:");
                                if ( t_check_trans() ) {
                                        t_relay();
                                        exit;
                                }
                                else {
                                        exit;
                                }
                        }
                        sl_send_reply("404","Not here");
