This will not work because msg_apply_changes is working only in request route. I do substr in reply routes also.
From documentation: "This function can be used from REQUEST_ROUTE or core REPLY_ROUTE."
It can't be used in any other "named" reply.
See: https://www.kamailio.org/wiki/cookbooks/5.1.x/core#reply_route reply_route{} is executed before any route armed with t_on_reply(), sou you can possibly rewrite your reply logic a little.
