Operator, the phone screen

Blocking spam callers one at a time never converges, because a dialer spoofs a fresh caller ID every time and every block you place lands on a number that no longer exists. So the default is inverted: an unknown caller has to prove they are a person with a reason before your phone makes a sound.

1. 1

   Allow list

   Rings straight through. No greeting, no screen. That silence is the point.

2. 2

   Block list

   Busy signal. The call is never answered, so it costs nothing.

3. 3

   Spoken screen

   Everyone else presses a named digit. A dialer is playing a recording, not listening to one, so it cannot pass. One retry, because a person can fumble a keypad.

4. 4

   AI intake

   Callers who pass are asked for a name, a company, and a reason.

5. 5

   Transfer or message

   Transfer with a whispered one-line summary, or a recorded message with its transcription, both filed on the call.

Each call carries what the carrier actually billed for it, read back after the call settles. That is the real figure, not an estimate off a rate table, and it covers the call minutes only.
