Definitely not adding it back anywhere. Is it possible that loose_route() or t_relay() would add it back? These are the relevant blocks of code this call is traversing.
xlog("L_ERR","We have a Proxy Route request, performing loose routing to end point [$(hdr(Route))]"); remove_hf("P-Proxy-Route"); remove_hf("Route");
if(loose_route()){ route(RELAY); }else{ sl_send_reply("404","Unable to route request"); }
route[RELAY]{ xlog("L_INFO", "Setting up reply handler and relaying request\n");
t_on_reply("LOG"); if(!t_relay()){ sl_reply_error(); } }

Hi Geoffrey,
it looks like you add the Route header somewhere else, since the Route-Header has a different position before and after Kamailio. Maybe a lookup (with Path?) or similar? If you want to remove a header, which you added previously in the routing logic, then you will have to apply the changes before removing the header again (msg_apply_changes())... better would be not adding the header at all.
Kind regards, Carsten

Can anyone tell me why Kamailio 4.0 is sending the INVITE out with the
Route
Header intact? The call is running through this block which I thought should remove it before sending it out. The far end is having a hard
time
dealing with the fact that the Route header is in there and we aren't looking for strict routing.
if(is_present_hf("P-Proxy-Route")){ xlog("L_ERR","We have a Proxy Route request, performing loose routing to end point [$(hdr(Route))]"); remove_hf("P-Proxy-Route"); remove_hf("Route");
if(loose_route()){ route(RELAY); }else{ sl_send_reply("404","Unable to route request"); } }Here is the inbound and outbound INVITE (I have removed hosts and IPs intentionally)
