This is a high tech solution which just won't work for lots of people. Example: The local medical practice uses simple mobile phones. Think old Nokia with 3-line menu to display and no camera. You want a call back from a doctor on call and have no internet access. How would you do any pre-auth/whitelist in that case? How would you do it if you only had a land-line on POTS? |
