[OpenSIPS-Users] Problem with add_rr_param() in v2.4.7

[Bogdan-Andrei Iancu]

Hi John,

Using the latest 2.4 from GIT with the default cfg, I simply added your 
lines instead on the record_route();

     # record routing
     if (!is_method("REGISTER|MESSAGE")) {
         record_route_preset("127.0.0.1:5060;transport=udp", 
"127.0.0.1:5060");
         add_rr_param(";r2=on");
     }


As a result, in the outbound INVITE, I got the RR hdrs:

Record-Route: <sip:127.0.0.1:5060;transport=udp;ftag=719688679;lr;r2=on>
Record-Route: <sip:127.0.0.1:5060;ftag=719688679;lr;r2=on>

Again, could you come up (starting from the default opensips.cfg) with a 
minimal cfg to show your issue ?
