end call work flow does not act when remote side hangs up first

[Mortaza Rohani]

Hello,

I'm using uccx 11.6 and have some end call actions to record call duration and ... in CRM. 
the problem is when the customer hangs up first, wokflow actions does not take occur. that's working when agent hangs up first form phone or finesse panel. is it a normal behavior or may be a bug?

Thanks.
