Hi,


I have the following script logic:

   if (method=="REGISTER") {
     setflag(6);
     fix_nated_contact();
     save_noreply("location");
     if(remove_hf("Contact")) {
       insert_hf("Contact: <sip:foo@bar>\r\n","CSeq");
     }
   }

   if (!t_relay()) {
     sl_reply_error();
   }

Packets coming out of OpenSER 1.1.0 dev16 box contain  
fix_nated_contact garbage
in a line that should be removed in remove_hf call.
