When using Kamailio at the edge - what's the best practice around how to advertise your Record-Route? I assume it's going to involve the use of a double-RR with both the public and private IPs. However, I'm running in AWS where the host doesn't have two interfaces with both a public and private IP. So, I set the host's public IP as the advertised address while Kamailio binds to the local IP.

But now how do I get Kamailio to know that it needs to double-RR in this case?

Thanks,
