Hi Bruce,
Get some ideas from here:

Also using DNS SRV is a good idea for use afront of multiple active proxies.

If I want to have multiple kamailio proxies in front of multiple media servers, can I balance them using plain old DNS behind a domain name?  If I wanted a specific proxy to be notified about an entire SIP dialog I could set the record route to use the public IP of the proxy that received the initial INVITE.

Could I leverage something like route53 tcp healthchecks to know if I should be failing over to another proxy?
