Hello, I have following problem: I used following code for bridging my current session to multiple Voip Phones in a freeswitch thread (same as bgapi): switch_ivr_originate(session, &peer_session, &cause, "user/60@192.168.1.50,user/61@192.168.1.50", timelimit, NULL, NULL, NULL, NULL, NULL, SOF_NONE,NULL) != SWITCH_STATUS_SUCCESS) Both Phones with number 60 and 61 rings. In a special case I need to know when the peer_session hanged up (channel is not ready any more). I use following code for controling my bridged session (The peer_session) in another Thread: while (!peer_session) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session Nebenstelle is NULL ... Wait\n"); Sleep(200); } switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session Nebenstelle is created from originate call! \n"); channelNebenstelle = switch_core_session_get_channel(peer_session); while(switch_channel_ready(channel) && switch_channel_ready(channelNebenstelle)) { // Communication : Sleep(200); } switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session or Peer Session hangsup!\n"); // doing something special ... My peer_session is NULL, but Communication is possible. Why is my peer_session always NULL ? Is there a better solution (example a core-function) for getting my current connected peer_session ? I have tried switch_ivr_find_bridged_uuid(my_uuid, other_uuid,255 ); and sessionNebenstelle = switch_core_session_locate(other_uuid); ... but I get the session, which have loosed the race. regards Achim Stamm -- Achim Stamm, Dipl.-Inform.
