[Freeswitch-users] Lose Race instead of missed call

[Peter Steinbach]

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 at 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 at 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

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

Any hints why this happens, or anyone has this scenario working?
