> Key: ASTERISK-21409
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-21409
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Channels/chan_iax2
> Affects Versions: 1.8.15.0, 11.3.0
> Environment: Debian Squeeze
> Reporter: Alec Davis
> Attachments: iax-lock-asterisk-11.txt, iax-lock-asterisk-1-8-15.txt
>
>
> Intermittently all IAX calls stop over the trunk.
> I think this is reproduced when a call is transferred back to the originating site, we have "transfer=on"
> Also happened with asterisk SVN-branch-11-r382514.
> Attached are the 1.8.15.0 lockup, and the 11-branch lockup.
