You are right in that the SIP channel doesn't bother with this. But  
there's another way.

Like most other things related to calls in Asterisk, this can be  
controlled in the dialplan.
Use the SIPPEER function to check if the peer is registered. If not,  
hangup without
answering. If it is, then process the call as usual.

If you want to, you can even play prompts or send the calls from  
unregistered
devices to the talking clock in London.

Some devices, like Linksys/Sipura, have settings of their own that  
block calls
if the device can't register.

Merry Christmas!
