interesting -- for me, it does generate the ACK. If it does not,
something is wrong.

there is certainly one shortcoming I'm aware of which is the ACK
is generated like ACKs for negative replies (ingoring dialog rules,
i.e., sending to the same destination as INVITE and ignoring route
set). That should not however prevent the ACK from being seen.

Can you send me the ngreps?

that's nice, please send it over to me.
