Actually it doesn't matter for me if it's active-passive as well. Just need to make sure no disaster since my whole SBC is depending on kamailio redirect server for passing traffic. Outbound route selection is mainly done by mySQL queries and my SBC, Genband S3 has ability to distribute invite to redirect servers. Do you think having two kamailio servers lined to culstered mySQL server is simplest and most reliable solution? Or any other better approach? Thanks,
Hi Maw,
we're using a pool of identical kamailio load balancers in front of our systems, requests are distributed to it by routing means or DNS. If one of this system fails or needs to be removed out of the pool (e.g. for maintenance) we just move its IP adress to one of the other active or spare machines. For more planned maintenance you can of course also use DNS to shift load from one machine to another.
Cheers,
Henning
