Hello,

you remove header Route and insert header Record-Route, is it what you wanted to do? Maybe removing same Record-Route header, but be careful in the case you have more than one proxy in the chain of signaling.

Cheers,
Daniel

Hello Daniel,
I end up insert routes like this.  And right now on client side I see only public ip route and private side only private ip routes.

route[ROUTE_HDR_ORG] {
        # Getting record routes
        if(is_present_hf("Route")) {
                xlog("L_INFO", "[$rm], Inbound connection from <$si>\n");
                if(is_method("NOTIFY")) {
                        if(is_ip_rfc1918($si)) {
                              xlog("L_INFO", "[$rm], Present Route: $(route_uri{uri.host})\n");
                              remove_hf("Route");
                              insert_hf("Record-Route: <"sip" + $sel(cfg_get.kamailio.bindpublicip) + ":" $sel(cfg_get.kamailio.bindpublicport);transport=tcp;lr=on;ftag=$ft;nat=yes>\r\n");
                             $fs = "tcp" + ":" + $sel(cfg_get.kamailio.bindpublicip) + ":" + $sel(cfg_get.kamailio.bindpublicport);
                        } else {
                             xlog("L_INFO", "[$rm], Present Route: $(route_uri{uri.host})\n");
                             remove_hf("Route");
                             insert_hf("Record-Route: <"sip" + ":" $sel(cfg_get.kamailio.bindip)  + ":" + $sel(cfg_get.kamailio.bindport);lr=on;ftag=$ft;nat=yes>\r\n");
                             $fs = "udp" + ":" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport);
                        }
                }
        }
}

And for initial SUBSCRIBE INVITE

        if (is_method("INVITE|SUBSCRIBE")) {
                remove_hf("Route");
                insert_hf("Record-Route: <"sip" + ":"  + $sel(cfg_get.kamailio.bindip)  + ":" + $sel(cfg_get.kamailio.bindport);lr=on;ftag=$ft;nat=yes>\r\n");
                #record_route();
        }

Hello,

but the INVITE request goes out with 2 Record Route headers, if you get them in the 200ok.

Not sure how it is going to work overall, you will have to manually set local sockets for requests within dialog, because you are doing also trasport layer gatewaying (tcp-udp).

Anyhow, as a solution, maybe you should just not be using record_route() function and just add the header with insert_hf() for the invite, remove the Record-Route header for 200ok with remove_hf() and insert a new one again with insert_hf()

If you know the local address (IP/port/transport) you want to put in the Record-Route, you can build the header as:

insert_hf("Record-Route: <sip:_LOCAL_IP_:_LOCAL_PORT_;transport=_LOCAL_TRANSPORT_;lr=on;ftag=$ft;nat=yes>\r\n");

Requests within the dialog can be handled with loose_route(), but again, you have to do more in config for selecting the local socket to send to next hop.

Cheers,
Daniel

Hello Daniel,
I want do clean up on routes from first SUBSCRIBE, that when traffic goes to public side of kamailio will be only public route and when traffic is internal the Record-Route will stay internal only.  In SDP I see like this.
I tired double routes set 0 in rr, but didn't clean enough.

Hello,

can you give an example of incoming header and how you want to be after modification?

It is not clear for me what end result you want/expect.

Cheers,
Daniel
