you can do this way, too, scaling better.

But I thought you want to preserve as much as possible current 
architecture. So the phones register to asterisk -- this to be done by 
configuring each phone to use the proper asterisk.

Once you add a new phone, you add a routing info in kamailio binding the 
phone id to asterisk ip (you can do that with alias_db, pdt, htable, and 
other modules, just a matter of taste).

In asterisk dialplan, if the dialed number is not a local phone, forward 
it to kamailio which will forward to right asterisk.

I can think of various options to optimize and auto-provision, like 
automatically updating kamailio's routing rules based on user registration.

Cheers,
Daniel
