Hi All, When kamailio(kamailio-5.0) receive 200 OK message, we need to send Rx_AAR for origin and term call. Rx_AAR("MT_aar_reply", "origin","",2); for origin call Rx_AAR("MT_aar_reply", "term","",2); for term call. But from source code ims_qos_mod.c, we see lots of part like below to not support for a request. Even we comments them, there are still lots of issues, could we support the scenarios like below: when kamailio receive 200 OK, we can send Rx_AAR for term and origin call. //We don't ever do AAR on request for calling scenario... if (msg->first_line.type != SIP_REPLY) { // Added by vlv // LM_DBG("Can't do AAR for call session in request\n"); // return result; } -- You are receiving this because you are subscribed to this thread.
