you must authenticate the call, this check comes after, to be sure the 
user is calling from a phone that was previously registered (so it is 
online).

If you check the discussions from the last days, one good thing of doing 
this is to prevent SIP Digest Access Authentication RELAY.

One can call from a sip phone even that phone is not registered 
(REGISTER-200ok).

Cheers,
Daniel
