There is an update. First I'll give you more information of what I'm
doing all this time. Inside on_call_state() I make a function call,
let's name it post_notificaton(), on the main thread. Inside that
there is a call to incoming_calls_count(). If I'm not waiting for
post_notificaton() to return, everything goes as I described.
But if I wait inside the thread of on_call_state() for
post_notificaton() to return, I'll get a deadlock at
pjsua_enum_calls(call_ids, &all_count); from incoming_calls_count().
