Hi, If the registration callback (pjsua_config.cb.on_reg_state2) is called with a failure, how to tell if the failure was for an unregister attempt or a register attempt? When I make a change to an account it?s going to trigger an unregister followed by a reregister but I don?t see how I can tell what stage the failure is for.
