Hello, we have some Problems with the right signalling of missed calls when calling multiple phones in parallel Here's the scenario: Phone no 49 is calling a group with 2170 and 3275 with the following dialstring <action application="bridge" data="{default_language=de,ignore_early_media=true,global_to_originate_1=true,caller_cc=49,callee_cc=49,routing_flags=INT-ONSYSTEM-RELIA0-QUAL0-T38NOLAST-CALLG-CALLG5003-UUID,call_timeout=60,originate_timeout=60,origination_caller_id_number=49,effective_caller_id_number=49,caller_uuid=7f49c581-cf47-429d-85a0-365d00ff031c,origination_uuid=59eee5e0-c0bc-0135-7dc9-00505600a1a5,sip_invite_domain=flex.mydomain.de,customer_id=261}user/2170@flex.mydomain.de:_:{default_language=de,ignore_early_media=true,global_to_originate_1=true,caller_cc=49,callee_cc=49,routing_flags=INT-ONSYSTEM-RELIA0-QUAL0-T38NOLAST-CALLG-CALLG5003-UUID,call_timeout=60,originate_timeout=60,origination_caller_id_number=49,effective_caller_id_number=49,caller_uuid=7f49c581-cf47-429d-85a0-365d00ff031c,origination_uuid=59f07af0-c0bc-0135-7dca-00505600a1a5,sip_invite_domain=flex.mydomain.de,customer_id=261}user/3275@flex.mydomain.de" /> Destination dialstrings are seperated by ":_:" ("Enterprise Origination"). We use curly brackets instead of "<" as we sometimes have to insert asserted identy tags into the dialstring. We checked 3 versions of Freeswitch for this Version Feb 2016 shows missed calls on both phones. Even if one phone answers, the other phone one still shows a missed call (reason for upgrading to newer Freeswitch) Version Aug 2017 never shows missed call, see logs and hangup message below Version 10/Dec 2017(yesterday) never shows missed call, as above So for the 2 never Freeswitch Versions, here are the logs at hangup 2017-12-11 17:07:46.022450 [DEBUG] sofia.c:7283 Channel sofia/internal/49@flex.mydomain.de:5060 entering state [terminated][487] 2017-12-11 17:07:46.022450 [NOTICE] sofia.c:8474 Hangup sofia/internal/49@flex.mydomain.de:5060 [CS_EXECUTE] [ORIGINATOR_CANCEL] 2017-12-11 17:07:46.042331 [NOTICE] switch_ivr_originate.c:3627 Hangup sofia/internal/2170@94.xx.xxx.xx:42170 [CS_CONSUME_MEDIA] [LOSE_RACE] 2017-12-11 17:07:46.042331 [DEBUG] switch_ivr_originate.c:3852 Originate Cancelled by originator termination Cause: 487 [ORIGINATOR_CANCEL] 2017-12-11 17:07:46.042331 [NOTICE] switch_ivr_originate.c:2866 Cannot create outgoing channel of type [user] cause: [LOSE_RACE] 2017-12-11 17:07:46.042331 [DEBUG] switch_ivr_originate.c:3863 Originate Resulted in Error Cause: 502 [LOSE_RACE] 2017-12-11 17:07:46.042331 [DEBUG] switch_core_state_machine.c:584 (sofia/internal/2170@94.xx.xxx.xx:42170) Running State Change CS_HANGUP (Cur 3 Tot 22) 2017-12-11 17:07:46.042331 [DEBUG] switch_core_state_machine.c:850 (sofia/internal/2170@94.xx.xxx.xx:42170) Callstate Change RINGING -> HANGUP 2017-12-11 17:07:46.042331 [DEBUG] switch_core_state_machine.c:852 (sofia/internal/2170@94.xx.xxx.xx:42170) State HANGUP 2017-12-11 17:07:46.042331 [DEBUG] mod_sofia.c:449 Channel sofia/internal/2170@94.xx.xxx.xx:42170 hanging up, cause: LOSE_RACE 2017-12-11 17:07:46.042331 [NOTICE] switch_ivr_originate.c:3627 Hangup sofia/internal/3275@94.xx.xxx.xx:43275 [CS_CONSUME_MEDIA] [LOSE_RACE] 2017-12-11 17:07:46.042331 [DEBUG] switch_ivr_originate.c:3852 Originate Cancelled by originator termination Cause: 487 [ORIGINATOR_CANCEL] 2017-12-11 17:07:46.042331 [NOTICE] switch_ivr_originate.c:2866 Cannot create outgoing channel of type [user] cause: [LOSE_RACE] 2017-12-11 17:07:46.042331 [DEBUG] switch_ivr_originate.c:3863 Originate Resulted in Error Cause: 502 [LOSE_RACE] Here is the Cancel message for one of the called phones: U 2017/12/11 17:07:46.045120 144.xx.xxx.xx:5060 -> 94.xx.xxx.xx:42170 CANCEL sip:2170@94.xx.xxx.xx:42170 SIP/2.0.
