>    Affects Versions: 13.0.0-beta1
>         Environment: Asterisk SVN-branch-13-r422905 
> Digium Phone Module for Asterisk Version 13.0_2.1.0-rc1

> when running asterisk_queue_test_two, the sequence of tests which exercise joinempty and leavewhenempty always cause SIP to deadlock. I.E., all phones become unregistered and no calls can be placed. I don't know the exact cause just yet.
