[Freeswitch-users] Correct way to hangup a channel

[Anthony Minessale]

look for something that calls either switch_core_session_locate
switch_core_session_get_partner or something that calls
switch_core_session_read_lock(session);  in all of these cases its
necessary to call switch_core_session_rwunlock(session); before letting the
session pointer go out of scope.
