I have pretty much ruled out OpenSER/OpenSIPS/Kamilio because it isn't stateful in HA failover.
Who said you can't make it that way, with a little effort? What state are you wanting to conserve?
Session state, so in the event the load balancers experience a failover, new messages within existing sessions (re-invite, refer, bye etc) are still routed appropriately. Obviously if the elements being load balanced across experience a failure, sessions on the failed element are gone, so I am not worried about that, just more about making the middle as invisible as possible.
