asterisk users - Nov 2016 - app_queue ringall - 2 agents answer same time problem

hi,

our customer reports problem when 2 agents answer the call in the same time

faster operator (device) answer the call, but the second is showed up 
(on device) and call is without sound

asterisk 13.9/app_queue with strategy ringall/operators via Local 
channel with sip device (chan_sip)

do you have any tips/info before i will dig deep into logs/debug?

checked google&issues.asterisk.org without any clue

marek

Your second call is not without sound, there is simply no call at all.
As the first answer the call his channel and the external call channel
connected.
The second device simply off hook but his channel have no external channel
to connect.

It's looks like a simple telephony glare.
