<p><tt>Hi, Giovanni!</tt></p>
<p><tt>Since you seem to be talking about a hop-by-hop ACK (ACK to a
[3456]xx SIP reply), I suspect this "if" condition is basically
catching your ACK too early, before you are able to ship it to
Homer:<br>
</tt></p>
<p><tt> ...<br>
if (has_totag()) {<br>
# handle hop-by-hop ACK (no routing required)<br>
if ( is_method("ACK") && t_check_trans() ) {<br>
t_relay();<br>
exit;<br>
}</tt></p>
<p><tt> ...</tt></p>
<p><tt>Hope this helps,</tt><br>
