Abhay Gupta commented on ASTERISK-28377:
----------------------------------------

I was trying with asterisk 15.6.1 and following the same sequence of inbound call which is not answered and then put that in bridge , create a channel , put that in same bridge , dial the channel which times out and then hangup all channels and delete bridge but i am not able to generate the issue .

> Using ARI
> 1) accept inbound channel
> 2) create outbound channel
> 3) bridge inbound channel to outbound
> 4) dial outbound and let dial timeout expire
> 5) hangup outbound channel and destroy bridge
> 5) hangup inbound channel
> This results in either messages like:
