What's the best way of doing OpenSER load balancing and failover ? I'm trying to do a DNS Round Robin with two OpenSER 1.3.2 but sometimes when a user registered on server1 tries to call a user at server2 the call is not completed. In this scenario I have a common MySQL cluster serving both OpenSER servers. Any help ?
