[OpenSER-Users] using remove_hf and append_hf in both route and failure route

[Mik Cheez]

I use remove_hf and append_hf to modify the RPID in the Request_Route, 
which works fine, but then if I try it in Failure_Route I end up with 
two RPID headers.

Is it possible the revert_uri() is doing something to it?  If not, can 
you just not do a remove/append like this?  I checked to make sure the 
remove_hf is returning true.  I triple checked to make sure my variable 
contains only one header.

Here are some snippets from my config:

route {
...
...
 if (method=="INVITE") {
  perl_exec("command", "0");  /*sets rpid and ouri vars*/
  if (is_avp_set("$avp(rpid)")){
    if(is_present_hf("Remote-Party-ID")){
        remove_hf("Remote-Party-ID");
    }
    append_hf("$avp(rpid)");
  }
  avp_pushto("$ru","$avp(ouri)");
...
...
failure_route[1]{
  if(method == "INVITE" ....blah blah blah
   revert_uri();
   perl_exec("command", "1"); /*sets rpid and ouri vars*/

   if (is_avp_set("$avp(rpid)")){
    if(is_present_hf("Remote-Party-ID")){
        remove_hf("Remote-Party-ID");
    }
    append_hf("$avp(rpid)");
   }
   avp_pushto("$ru","$avp(ouri)");
...
...

Best regards,
