Roel van Meer commented on ASTERISK-23130:
------------------------------------------

The orphaned channels look like this:

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/Transfers, Resources/General, Resources/res_parking
>    Affects Versions: 1.8.25.0
>         Environment: Slackware linux 13.1, 64-bit, kernel 3.4.45
>            Reporter: Roel van Meer
>            Severity: Minor
>         Attachments: debug.txt, extensions.conf
>
>
> Symptoms: Asterisk uses 100% CPU and has orphaned channels that don't go away.
> Environment: asterisk, two SIP phones (A and B), call parking on extensions 100-106
> How to reproduce (short version):
> Program a button of phone B as speed dial to 101.
> Use phone A to dial B
> Use asterisk attended transfer to transfer the call to the parking extension (100).
> You'll hear the announcement of the extensions where the call is parked.
> Don't hang up!
> Now press the speed dial button for extension 101.
> Both calls are now hung up. The asterisk process is using 100% CPU. There are no parked calls, but there are still two active channels.
