Review request for Asterisk Developers.


Changes
-------

Updated per findings.


Bugs: ASTERISK-24514
    https://issues.asterisk.org/jira/browse/ASTERISK-24514


Repository: Asterisk


Description
-------

When using a non-default sorcery wizard (in this instance realtime) for outbound publishes Asterisk will crash after a stack overflow occurs due to the code infinitely recursing.  The fix entails removing the outbound publish state dependency from the outbound publish sorcery object and instead keeping an in memory container that can be used to lookup the state when needed.


Diffs (updated)
-----

  branches/13/res/res_pjsip_outbound_publish.c 428998 

Diff: https://reviewboard.asterisk.org/r/4178/diff/


Testing
-------

On top of running the current testsuite tests I also manually tested various configurations and scenarios using a static configuration file as well as dynamic realtime.  Verified that the crash no longer occurs and the potentially affected functionality works as expected (for instance, module [re]loading).


Thanks,

Kevin Harwell
