That is working, however, on subsequent messages in the dialog (e.g., ACK, INFO, BYE) the
proxy tries the failed destination for each message. Eventually it gets to the right
place, but, is there a way to delete the failed destination from the XAVP so this
doesn't happen? Or just to force subsequent messages in the transaction to use the
same (working) destination?
Sorry for all the questions, I'm a newbie!
Not at all!
Forcing subsequent in-dialog messages to go to the same destination is inherent to correct
proxy behaviour; it just requires some additional logic that is part of typical Kamailio
boilerplate. (You can only get away with having a 'minimalistic' config for so
long. :)
Check this out:

You'll want to put that near the top of your config, well before you handle any
initial INVITEs.
A simplified version that will work for your purposes:
if(has_totag()) {
if(loose_route()) {
if(!t_relay())
sl_reply_error();
exit;
} else if(is_method("ACK")) {
if(t_check_trans()) {
if(!t_relay())
sl_reply_error();
exit;
}
exit;
}
sl_send_reply("404", "Not here");
}
