t_relay does not even return for ACK:

if (is_method("INVITE")) {
         $avp(revdir) = 11;
}

if (is_method("ACK")) {
         $avp(revdir) = 12;
}

xlog("L_NOTICE","$rm before t_relay(): $$avp(revdir) = $avp(revdir) ...\n");
if (!t_relay()) {
         xlog("L_NOTICE"," t_relay() failed, sending stateless reply 
...\n");
         sl_reply_error();
}
xlog("L_NOTICE","$rm after t_relay(): $$avp(revdir) = $avp(revdir) ...\n");
exit;


results in:


INVITE before t_relay(): $avp(revdir) = 11 ...
INVITE after t_relay(): $avp(revdir) = 11 ...
ACK has totag ...
ACK has totag and is loose-routed ...
ACK before t_relay(): $avp(revdir) = 12 ...


Thus, the xlog after t_relay() is not executed for ACK.

following is the log output of debug=4 during t_relay() of the ACK.
