[asterisk-bugs] [JIRA] (ASTERISK-23130) Transfer of parked call causes 100% CPU and orphaned channels

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=214008#comment-214008 ] 

Matt Jordan commented on ASTERISK-23130:
----------------------------------------

In ASTERISK-23047 and ASTERISK-22834, the transfer was initiated by chan_sip. In your case, you're initiating it via core DTMF features, so I'm not surprised the patch didn't resolve your issue.

That being said, unfortunately, your DEBUG log isn't a properly generated DEBUG log - a DEBUG log doesn't mean just DEBUG statements, but DEBUG statements and higher - that is:

{noformat}
full => debug,verbose,notice,warning,error,dtmf
{noformat}

Instructions for generating a DEBUG log are on the Asterisk wiki:

Please attach the new log illustrating the problem. That should help us find where in the features the off nominal path isn't being handled correctly.

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/Transfers, Resources/General, Resources/res_parking
>    Affects Versions: 1.8.25.0, 11.7.0
>         Environment: Slackware linux 13.1, 64-bit, kernel 3.4.45
>            Reporter: Roel van Meer
>            Assignee: Rusty Newton
>            Severity: Minor
>         Attachments: ASTERISK-23047-1.8.diff, 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.
