AFAIK kamailio rr module adds 2 RR headers (one with the inbound address and one with the outbound address) when your transaction comes with one interface/port and leaves via another.
In EC2 the receive socket is the same as send socket and I've had no luck trying to get kamailio insert advertised address as inbound RR and then the outbound RR, by calling record_route_preset() several times in a row too. This is a problem if lb is in front of another proxy.
In the final SPCE v2.2 (to be released next week) we do it manually using insert_hf(). It's ugly, but it works. Note that this is not there yet in v2.2-rc1. Anyways, it looks like this (using template-toolkit, for those who don't know the SPCE):
[% IF networking.aaddress %] insert_hf("Record-Route: <sip:[% networking.aaddress %]:[% kamailio.lb.port %];lr;r2=on>,<sip:[% networking.iaddress %]:[% kamailio.lb.port %];lr;r2=on>\r\n"); [% ELSE %] record_route(); [% END %]
You need to check the direction of the message also to put the addresses into the right order.
In the latest Kamailio trunk, RR module supports adding two Record-Routes using record_route_preset(), see http://kamailio.org/docs/modules/devel/modules_k/rr.html#id2784744 .
