after going to lookup("location") and forwarding for the first time the 
INVITE, set a failure_route with:

t_on_failure("REDIRECT_BUSY");

before doing the t_relay().

Then, define the failure_route like:

failure_route[REDIRECT_BUSY] {
    if(t_check_status("486")) {
        $ru = "sip:foo at bar.com";
        t_relay();
    }
}

Cheers,
Daniel
