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 registrations and after adding in an appropriate call to ast_sorcery_apply_config() (since it is missing) Asterisk will crash after a stack overflow occurs due to the code infinitely recursing.  The fix entails removing the outbound registration state dependency from the outbound registration sorcery object and instead keeping an in memory container that can be used to lookup the state when needed.

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, cli/ami commands, module [re]loading, and manual unregistration).


Thanks,

Kevin Harwell
