Hi, Giovanni!

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:

     ...
     if (has_totag()) {
         # handle hop-by-hop ACK (no routing required)
         if ( is_method("ACK") && t_check_trans() ) {
             t_relay();
             exit;
         }

     ...

Hope this helps,
