I've been pondering an issue with Route header parameters being not mirrored by kamailio proxy into Record-Route field on in-dialog requests over the last few hours so I thought I'd just whether I'm missing something obvious.
The call scenario in UA -> lb -> proxy -> sems. Everything is fine with initial INVITE transaction where we add rr param ;rtpprx=yes. (We also use dialog module.) The UA does re-INVITE where it mirrors RR headers to Route set just fine. However, when forwarding re-INVITE kamailio proxy removes own Route header and inserts RR header without rtpproxy, did etc params. The kamailio default config from branch 3.1 routes in-dialog requests in the same fashion and I can't tell really if this is how it is supposed to work? I can workaround this by add_rr_param() but shouldn't missing did param cause a problem with dialog matching?
