Hi Alex, we've tested the suggested changes and it works great!

I've called `set_contact_alias()` in `reply_route` and `handle_ruri_alias()` in `if(loose_route()) ...`, and that solved the problem - the `ACK` is now sent correctly to the IP address that sent the reply.

Great job and thank you very much.

BTW, Nir S. sends his regards.

Cheers!

Try set_contact_alias() (it might make more sense than
add_contact_alias() here, though they are substantially the same) in the
onreply_route handling both the 18x and the 200 OK, and call
handle_ruri_alias() in the section of the config with loose_route()
route and friends, which handles in-dialog request routing.

One nice thing about handle_ruri_alias() is it silently returns if there
is no ;alias URI parameter, so you can call it without a bunch of
conditional logic around whether it is appropriate to call it.
