Hi

I think you can use the t_replicate function within your register route so
that each server will replicate the registration request to the other.

I did this many years ago on OpenSER using the following just before the
consume_credentials() line.

On each of the servers you want to check that the src_ip is not that of the
OTHER sever so they don't keep sending back and forth forever :-) So in the
example below 10.0.1.1 is the IP of the other server.

--------8<-----------------------------------------
       if (!src_ip==10.0.1.1) {
               t_replicate("udp:10.0.1.1:5060");
               xlog("L_INFO", "Replicating $ct, URI = $ru");
       };

       consume_credentials();
--------8<-----------------------------------------

Have a look at
http://www.kamailio.org/docs/modules/3.3.x/modules/tm.html#t_replicate

Hope this helps.
