[SR-Users] Authentication and outbound proxy

It sounds like I should take a different approach. I'd like to avoid any 
comparability issues. I'm thinking I could filter the traffic in 
Kamailio based on destination SIP proxy. This would at least lock down 
Kamailio to only proxy "whitelisted" destinations.

Are there any best practices for a setup like this?
