<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This has the possibility to return two different types. Retrieving a registration from sorcery will retrieve a sip_outbound_registration. Finding an object in the current_states container will get a sip_oubound_registration_state</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Actually it only returns the registration or NULL. The call to ao2_find is an attempt to remove the state from current_states if no registration exists. However as this may be unclear I added a comment.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">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.</pre>

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).</pre>
