Hi Juan,

you don't need to combine all carriers together. If you want to priorize over 
different carriers, then i'd suggest you also use them in cr. For example 
something like this:

- carrier premium; domain 0, 1, 2; GWs a1, a2, a3, b1, b2, b3..
- carrier standard; domain 0, 1, 2; GWs A1, A2, A3, B1, B2, B3..

Then you could use different domains to implement your failover over the 
different GWs. And also of course do your prefix matching to route your calls 
to the best GW.

If you want to use only one carrier, then you also could just load the domain 
with DB avpops from some table, and just give the AVP to the cr_route 
function. You don't need to use the cr_user_carrier function, this is 
provided mainly for convinience and backward compatiblity.

Cheers,

Henning
