Hello,

Sorry for the late reply, I was a little busy by something else.

Yes I have #!KAMAILIO at the beginning of my kamailio.cfg.

Also, someone notided me that it could be a better idea to do a proper
dialog establishment and try to end it after that, for example with
dlg_bye("all");
So I think I will try to use something like :

#!ifdef WITH_MEDIA_PROXY

        if (is_method("INVITE") && status == "200") {
                use_media_proxy();
                if($rc < 0) {
                        xlog("L_ERR", "invite reply error,
use_media_proxy() failed with $rc \n");
                        if (dlg_get("$ci", "$ft", "$tt"))
                        {
                                xlog("L_DBG", "ending a new dialog\n");
                                dlg_bye("all");
                        }
                }
        }
#!endif

Anyone has ever tried something like that ?

Thanks,
