Making MESSAGE_SEND_STATUS reflect whether the message was sent or not for
PJSIP was merged in 2 days ago[1]. It will be in a future release. If you
don't want to wait you could use device state to know if the device is
reachable (and thus a MESSAGE has a chance of being sent) using the
DEVICE_STATE dialplan function[2].
