Hello everybody! Kamailio works as a Registrar. Additionally, rtpengine is deployed next to it. Using rtpgngine module I proxy media stream via rtpengine(rtpengine_manage()). I change SDP. SiP2SIP calls work fine. Now I would like to have possibility to "wake up" sip-clients(at the android and ios phones) which are usually not on-line via push notification. Trying to use TSILO module. # User location service route[LOCATION] { lookup("location"); $var(rc) = $rc; if (is_method("INVITE")) { if (t_newtran()) { ts_store(); # if it a new transuction ,it will be store for some time. } } switch ($var(rc)) { case 1: route(RELAY); break; case -1: break; case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } }
# Handle SIP registrations route[REGISTRAR] { if (!is_method("REGISTER")) return; if (!save("location")) { sl_reply_error(); } ts_append("location", "$tu"); # if transuction for this sip-client is exist. The invite will be send. exit; }
If the client is not registered at the kamailio during the call. Then such calls are stored through the "ts_store" function for some time. And if during this time the client send register, kamailio will be sent INVITE to it. But I have the problem. Such calls after "wake up"go through a special branch route that I don't know how to intercept. As a result, I can't change SDP(using rtpengite_manage commands) and rtp stream do not proxy via rtpengine… and call failed. /usr/sbin/kamailio[9957]: exec: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} *** cfgtrace:request_route=[REGISTRAR] c=[/etc/kamailio/kamailio.cfg] l=428 a=26 n=ts_append /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tsilo [ts_append.c:72]: ts_append(): transaction 36343:92182831 found for 777777777, going to append branches /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_lookup.c:1629]: t_lookup_ident_filter(): transaction found /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} registrar [lookup.c:255]: lookup_helper(): contact for [777777777] found by address /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} registrar [lookup.c:456]: lookup_helper(): instance is /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_append_branches.c:77]: t_append_branches(): transaction 36343:92182831 in status 0 /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_append_branches.c:99]: t_append_branches(): Call uvAzTGsEV9N2ReDjmWoo8A..: 0 (1) outgoing branches /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_append_branches.c:126]: t_append_branches(): Current uri sip:77777777@95.165.146.181:63618;transport=TCP;rinstance=8b1865b95767b7ba /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} <core> [core/msg_translator.c:2933]: create_via_hf(): id added: <;i=1>, rcv proto=2 /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_append_branches.c:149]: t_append_branches(): added branch [sip:777777777@95.165.146.181:63618;transport=TCP;rinstance=8b1865b95767b7ba] with ruid [uloc-5dd2faa0-26e5-1] /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} tm [t_append_branches.c:163]: t_append_branches(): Call uvAzTGsEV9N2ReDjmWoo8A..: 0 (0) outgoing branches after clear_branches() /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} <core> [core/tcp_main.c:2238]: tcpconn_send_put(): send from reader (9957 (22)), reusing fd /usr/sbin/kamailio[9957]: DEBUG: {1 2 REGISTER JxPcA9D1hIJ8PmkcnOvI7g..} <core> [core/tcp_main.c:2473]: tcpconn_do_send(): sending... -- Oleg Podguyko
