I understood Alfonso's question to implicitly be: how can I add a
dynamic and variable Reason header to outgoing CANCELs?

Perhaps I was mistaken. But if I'm not, as far as I know there is no
means of doing that. Right?

I've tried to see if I could do it in the onsend_route, but that one is not triggered for the generated CANCEL. I also checked event_route[tm:local-request], but that one isn't triggered either for the generated CANCEL.
