Conferences are reference counted objects. When the reference count reaches
0 on the conference object, its destructor is automatically called. The
destructor, in this case, is destroy_conference_bridge. That is where the
CBAnn channel should be hung up.
/* Try to allocate memory for a new conference bridge, if we
fail... this won't end well. */
if (!(conference = ao2_alloc(sizeof(*conference),
destroy_conference_bridge))) {
ao2_unlock(conference_bridges);
ast_log(LOG_ERROR, "Conference '%s' could not be created.\n",
conference_name);
return NULL;
}
If the reference count on the bridge is off, you should see the conference
bridge 'hanging around' after the last participant has left. If so, please
file a bug report. We'll need a REF_DEBUG log to figure out who the guilty
party is in holding onto a reference. The easiest way to get that is to
reproduce the problem using the latest from the 12 branch (as we made
reference count debugging easier just recently). Enable REF_DEBUG in
menuselect under Compiler Flags, make/make install, and re-run the scenario
that reproduces the result. A refs file will be created in your Asterisk
log directory - attach that to the issue along with DEBUG log.
Thanks!
