> While testing workarounds for ASTERISK-19493, I discovered another bug related to ChanSpy + Local channels. It is very similar to ASTERISK-19386, but the steps mentioned in that bug no longer reproduce the issue. The steps below, however, still do.
> Create 3 sip users, 'caller', 'agent' and 'supervisor' and log onto them with a SIP phone.
> Create extensions.conf:
> {quote}
> [incoming]
> exten => caller,1,Queue(queue1)
> exten => supervisor,1,ChanSpy(Local/s at phones,qsES)
> [phones]
> exten => s,1,Set(GROUP()=agent)
> exten => s,n,Dial(SIP/agent)
> {quote}
> Queues.conf:
> {quote}
> [queue1]
> member => Local/s at phones/n
> {quote}
> Then reproduce the issue as follows:
> - On the caller phone, dial 'caller' to get into the queue
> - On the agent phone, answer the queue call
> - On the supervisor phone, dial 'supervisor' to start the ChanSpy
> - Hang up the queue call
> Around 25% of the times, the bug will manifest: the GROUP on the local channel never gets cleared even though the channel itself h:
