[OpenSIPS-Users] add_rr_param(";r2=on"); not adding

[James Hogbin]

My script has

if (is_method("INVITE") && !has_totag() && check_source_address(0)) {
        xlog("[ROUTE]Incoming call to MS: RURI=$ruri, SI=$si, M=$rm\n");
        trace("tid");
        create_dialog();
        do_routing(1);  
        strip(1);
        prefix("+44");
        record_route_preset("sbc.ip-sentinel.com:5091;transport=tls", "10.0.0.5:5060");
        add_rr_param(";r2=on");
        route(relay);

Which is turning this:

BUT the Record routes do not have ;r2=on in them

I think this is causing an issue with ACK & BYE from the PBX hanging off the 5050 port
