[SR-Users] how to achive destination number based routing before falling back to dispatcher-module

[Christoph Russow]

Hi all,

im fairly new to Kamailio and currently setting up our new sip-server 
systems so, hello everyone!

right now i have a Kamailio SBC which routes all calls using the 
dispatcher module to our internally setup application servers (freeswitch).

i just got the idea that we might want specific routing based on 
destination phone number in addition to simple loadbalancing.

can anyone point me in the right direction where i should look for 
something i can place before the dispatcher routing to route calls based 
on some entries in a database like destination number XYZ goes to server 
A, number ABC goes to server Z and so on.

Or is there a way to select the dispatcher group id from the database 
based on destination number?

best regards
Christoph
