Hello all together! I started to operate FreeSwitch with live traffic for the first time yesterday. There is nothing special with my setup beside I used mod_h323. After some hours of operation the termination for all calls failed. In my CDR I find: hangup_cause_q850="27", hangup_cause="DESTINATION_OUT_OF_ORDER", sip_hangup_disposition="send_refuse". In freeswitch.log I find a lot of entries like: 2010-09-13 23:45:59.916855 [DEBUG] switch_core_state_machine.c:338 (sofia/external/9999#24107363687@xx.xx.xx.xx) State INIT 2010-09-13 23:45:59.916855 [DEBUG] mod_sofia.c:83 sofia/external/9999#24107363687@xx.xx.xx SOFIA INIT 2010-09-13 23:45:59.916855 [CRIT] sofia_glue.c:743 No RTP ports available! 2010-09-13 23:45:59.916855 [ERR] sofia_glue.c:1646 Port Error! 2010-09-13 23:45:59.916855 [DEBUG] switch_channel.c:2322 (sofia/external/9999#24107363687@xx.xx.xx) Callstate Change DOWN -> HANGUP and 2010-09-13 23:48:05.038734 [ERR] mod_h323.cpp:2013 h323/12424669543 Unsupported ptime of 2 on write Audio codec G.729{sw} for connection [0x2aaac01d2500] 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2017 h323/12424669543 initialise write codec Audio for connection [0x2aaab00e9d18] 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2072 Set write Audio codec to G.729{sw} for connection [0x2aaac01d2500] 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2078 ------------------->tech_pvt->rtp_session = [(nil)] 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2079 ------------------->samples_per_packet = 160 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2080 ------------------->actual_samples_per_second = 8000 2010-09-13 23:48:05.038734 [DEBUG] mod_h323.cpp:2127 ------------------------->tech_pvt->rtp_session = (nil) 2010-09-13 23:48:05.038734 [ERR] mod_h323.cpp:2132 AUDIO RTP REPORTS ERROR: [Missing local port] 2010-09-13 23:48:05.038734 [DEBUG] switch_channel.c:2322 (h323/12424669543) Callstate Change DOWN -> HANGUP 2010-09-13 23:48:05.038734 [NOTICE] mod_h323.cpp:2133 Hangup h323/12424669543 [CS_INIT] [DESTINATION_OUT_OF_ORDER] After a restart of FreeSwitch, it is working again.
