Thanks Klaus. The config already had several mentions of force_rport()
but it none before or during the INVITE handler. I've added it like
so:

route {
 ...
 force_rport();

 # -----------------------------------------------------------------
 # Call Type Processing Section
 # -----------------------------------------------------------------
 if (uri!=myself) {
         route(4);
         route(1);
         return;
 };

 if (method=="ACK") {
         route(1);
         return;
 } else if (method=="CANCEL") {
         route(1);
         return;
 } else if (method=="INVITE") {
         route(3);
         return;
 } else  if (method=="REGISTER") {
         route(2);
         return;
 };
 ...
}

Does that seem reasonable? It's going to force_rport() for every call,
NATed, PATed or not. Perhaps I should add a block to deal with NAT
traversal prior to routing the call according to message, something
like:

route {
 ...
 if (nat_uac_test("19")) {
         setflag(6);
         force_rport();
         fix_nated_contact();
 };

 # -----------------------------------------------------------------
 # Call Type Processing Section
 # -----------------------------------------------------------------
 if (uri!=myself) {
         route(4);
         route(1);
         return;
 };
 if (method=="ACK") {
         route(1);
         return;
 } else if (method=="CANCEL") {
         route(1);
         return;
 } else if (method=="INVITE") {
         route(3);
         return;
 } else  if (method=="REGISTER") {
         route(2);
         return;
 };
}

Thanks for any help,

Mark
