I've a kamailio setup for this scenario. We have two providers and 
incoming and outgoing calls that our kamailio route to the same asterisk 
every time.

We solved it with a custom database table for our routing and avpops for 
the queries:

I've read that sqlops are more efficient, so maybe you should evaluate 
that first:

Also, you could cache the information using a htable, but for me it's 
completly acceptable to have a sql query for each call.

The custom config is a good starting point, you just change $ru to the 
asterisk's sip-address and run t_relay(). This is the default in the 
route[RELAY]-block, so I just verify that the request is ok, and run
