A question: why exactly do you need to register a phone if it won't receive 
calls?

I think it depends on "location" table order. Probably the one with lower "id" 
value.

For that you need to use LCR module and funtions load_contacts() and 
next_contacts().
Look for it in the wiki and in Google, there are some working examples.

I just don't understand why do you need a phone registered if it won't receive 
calls. I assume you know that it not necessary to be registered in order to 
call.
