Hi all, I'm using Freeswitch with a few Javascript scripts like automatic phone dialer. Sometimes, when called party is BUSY, FS reports "Duplicate UUID!" error and the session was ended with case DESTINATION_OUT_OF_ORDER. This is contents of console from yesterday: 2016-07-27 20:46:56.249500 [INFO] amds.js:315 {origination_uuid=82b8a17d-c627-45dd-9eaf-86e9f31c57b1,origination_caller_id _number=950330980,origination_caller_id_name=AMDS}sofia/gateway/gw91/0725045 121|sofia/gateway/gw90/0725045121 2016-07-27 20:46:56.249500 [NOTICE] switch_channel.c:1105 New Channel sofia/external/0725045121 [82b8a17d-c627-45dd-9eaf-86e9f31c57b1] 2016-07-27 20:46:57.789511 [NOTICE] sofia.c:7891 Hangup sofia/external/0725045121 [CS_CONSUME_MEDIA] [USER_BUSY] 2016-07-27 20:46:57.799501 [CRIT] switch_core_session.c:2232 Duplicate UUID! 2016-07-27 20:46:57.799501 [CRIT] mod_sofia.c:4456 Error Creating Session 2016-07-27 20:46:57.799501 [NOTICE] switch_ivr_originate.c:2762 Cannot create outgoing channel of type [sofia] cause: [DESTINATION_OUT_OF_ORDER] 2016-07-27 20:46:57.799501 [NOTICE] switch_core_session.c:1664 Session 9903 (sofia/external/0725045121) Ended 2016-07-27 20:46:57.799501 [NOTICE] switch_core_session.c:1668 Close Channel sofia/external/0725045121 [CS_DESTROY] 2016-07-27 20:46:57.799501 [NOTICE] amds.js:86 Script exited with info [] Can anyone say what is wrong?
