The call notification messages are unsolicited. You can issue another
request and you get back a call notification too. This is why it implemented
as a callback function. IMHO putting inside data isn't good. And there's
another state dependent things which can be different between phones
(e.g. OnSMS callback). And what about the nokia authentication protocol?
Where can we store MagicBytes? Some messages handled differently depending
on the state (e.g. "dropping it" or "doing something" are trivial cases).
