A redirect is acomplished by manipulating $ru (or its parts $rU/$rd/...) and 
instead of relaying the request (t_relay()) sending a 302 Redirect 
(send_reply("302", "Redirect")). This has to be handled from the 
request_route.

You could use the alias_db module 
http://www.kamailio.org/docs/modules/4.1.x/modules/alias_db.html

request_route {
#do stuff

   if(alias_db_lookup("dbaliases"))
   {
      send_reply("302", "Redirect");
   }
   else
   {
      send_reply("404", "Unknow destination");
   }

   exit;
}
