Hi! I have just experienced some call drops and each time the sequence is the same in the freeswitch.log file. Both parties are sure that they did not accidentally hit the 3 button to send the DTMF tone (and the same thing has happened four times already after ~5 minutes). 2009-09-13 19:28:23.835216 [DEBUG] sofia.c:4329 INFO DTMF(3) 2009-09-13 19:28:23.835216 [DEBUG] sofia.c:4450 dispatched freeswitch event for INFO 2009-09-13 19:28:23.859408 [DEBUG] switch_rtp.c:1624 Send start packet for [3] ts=2591120 dur=160/160/13120 seq=64923 2009-09-13 19:28:23.879439 [DEBUG] switch_rtp.c:1560 Send middle packet for [3] ts=2591120 dur=320/320/13120 seq=64924 2009-09-13 19:28:23.899455 [DEBUG] switch_rtp.c:1560 Send middle packet for [3] ts=2591120 dur=480/480/13120 seq=64925 : : 2009-09-13 19:28:25.439404 [DEBUG] switch_rtp.c:1560 Send middle packet for [3] ts=2591120 dur=12800/12800/13120 seq=65002 2009-09-13 19:28:25.459312 [DEBUG] switch_rtp.c:1560 Send middle packet for [3] ts=2591120 dur=12960/12960/13120 seq=65003 2009-09-13 19:28:25.479183 [DEBUG] switch_rtp.c:1560 Send end packet for [3] ts=2591120 dur=13120/13120/13120 seq=65004 2009-09-13 19:28:25.479183 [DEBUG] switch_rtp.c:1560 Send end packet for [3] ts=2591120 dur=13120/13120/13120 seq=65005 2009-09-13 19:28:25.479183 [DEBUG] switch_rtp.c:1560 Send end packet for [3] ts=2591120 dur=13120/13120/13120 seq=65006 2009-09-13 19:28:33.879341 [NOTICE] sofia.c:322 Hangup sofia/external/<number> [CS_EXCHANGE_MEDIA] [NORMAL_CLEARING] 2009-09-13 19:28:33.879341 [DEBUG] switch_channel.c:1683 Send signal sofia/external/<number> [KILL] 2009-09-13 19:28:33.879341 [DEBUG] switch_core_session.c:932 Send signal sofia/external/<number> [BREAK] 2009-09-13 19:28:33.900940 [DEBUG] switch_ivr_bridge.c:371 sofia/external/<number> ending bridge by request from write function 2009-09-13 19:28:33.900940 [DEBUG] switch_ivr_bridge.c:426 sofia/internal_nat/1000@192.168.1.120 receive message [UNBRIDGE] 2009-09-13 19:28:33.900940 [DEBUG] switch_core_session.c:630 Send signal sofia/internal_nat/1000@192.168.1.120 [BREAK] 2009-09-13 19:28:33.900940 [DEBUG] switch_ivr_bridge.c:452 BRIDGE THREAD DONE [sofia/internal_nat/1000@192.168.1.120] 2009-09-13 19:28:33.900940 [DEBUG] switch_ivr_bridge.c:454 Send signal sofia/external/<number> [BREAK] 2009-09-13 19:28:33.912049 [NOTICE] switch_core_state_machine.c:179 Hangup sofia/internal_nat/1000@192.168.1.120 [CS_EXECUTE] [NORMAL_CLEARING] Anyone have any idea what this sequence means and why I am getting this? Is it my sip provider or something in FreeSwitch? What does the 'Send end packet for [3] ts=2591120 dur=13120/13120/13120 seq=65006' mean? Notice that dur (duration?) is increasing a lot until the call drops. Thanks!
