Hi Alex,

Thanks for the quick response. I believe I used the wrong terminology. Your sample code looks like exactly what I'm looking for. Thanks.

Regards,
Jay

Are you sure "reinvite" is the correct term for what you are referring to?

A reinvite is an INVITE inside a dialog. A dialog only exists between
two parties. So, sending it to a different gateway than the one in
relation to which the dialog already exists is not going to work.

That said, you can always fork new branches in a failure_route:

route {
    ...

    t_on_failure("FAILURE");

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

failure_route[FAILURE] {
    if(t_is_canceled())
      exit;

    $ru = "<new destination>":

    t_on_failure("FAILURE");
    t_relay();
}
