You need an onreply_route, like

onreply_route[1] {
  # strip +
  .........
}


and after prepending + in your route you have to call t_on_reply("1");, 
for example

route {
 .....
# prepend +
t_on_reply("1");
 .....
}

Anyhow, you should not touch the From and To headers, that may introduce

a lot of interoperabilities. Why changing the request URI is not enough?

>From and To are mostly used to identify the dialog by the clients.
