I agree with Inaki. We did exactly the same.

Subject: Re: [Sip-implementors] Response code sent by proxy to caller when UAS 
not registered

When a call comes into our system, we do look up whether this number is ours
or not. If it is not our number, we would return SIP 404. Then we check the
presence server to see if the device is registered. If it is not, we send
back SIP 480. A peer of ours is sending back SIP 403 in this case, which
does not seem to fit with the specs in any manner.
