Have you tried just record_route() with enable_double_rr option enabled? All things considered, RR should take care of it all by itself, per branch.

A script snippet could help.

Hello,

Thank you, added it now - still the same, unfortunately.

Have you tried calling t_save_lumps() before relaying, even before RR?

Hello,

Is there any way to advertise a different IP Address in the Record-Route header individually per branch?

I have a setup here - where Kamailio is listening on 2 different interfaces: Local IP and External IP. At the moment if the packet is coming through the internal interface - I'm checking where is it going to and based on that I'm setting the Record-Route header accordingly - and everything works well, except when I have multiple branches: one going through the internal interface and another one through the external one, so in this case, I have to add a different record-route header per branch, by doing this in the branch_route - it's not working and getting the error: w_record_route_advertised_address(): Double attempt to record-route.

What would be another way to accomplish this?
