You have to decide if it is hot-standby or cold standby. Mostly cold-standby is used. That means only one SIP proxy is running. The SIP proxy is using a virtual IP address. If the proxy fails (or the hardware fails) the standby server will detect this, will configure the virtual interface and start the SIP proxy. Take a look at "heartbeat" and "ultramonkey". If you are using hat standby, you configure the "fallback2db" option and either - use a single database - use 2 databases with master-master replication - use a mysql cluster regards klaus _______________________________________________ Users mailing list Users@lists.kamailio.org http://lists.kamailio.org/cgi-bin/mailman/listinfo/users
