[SR-Users] Kamailio as inbound and outbound proxy

[Alex Balashov]

You need two Record-Route headers, one for the ingress interface and one 
for the exit interface. They are added in a different order depending on 
which exit interface is used.

Fortunately, there is an option for just that, and it's on by default:
