The approach of prompting the user "Do you want to call this number?" is far simpler and safer. After all, you could probably use tel: links or tel: redirects or something if the frame didn't work.
It seems to me that there's no reason at all to allow URI's beginning with tel: as the source of a frame. Surely that's a fair limitation?
