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:

Hello,
I am trying to configure Kamailio as both an inbound and outbound proxy.
Inbound requests flow Sip Trunk -> Kamailio -> Asterisk. Outbound
requests flow Asterisk -> Kamailio -> Sip Trunk. Inbound traffic is
sent to port 5060 on kamailio which listens on the PRIVATE_IP:5060 and
advertises PUBLIC_IP:5060. How can we ensure that when messages are
sent to the Sip Trunk they have Record-Route headers with the PUBLIC_IP
and when messages are sent to asterisk they have Record-Route headers
with the PRIVATE_IP?
