Call CAPTCHA
What is a Call CAPTCHA?
A Call CAPTCHA is a voice security feature that helps protect your phone system from spam and robocalls. Similar to the CAPTCHAs you encounter on websites (e.g., "I'm not a robot" checkboxes), Call CAPTCHA challenges the caller with a simple test—like pressing a specific key—to confirm that the caller is human before allowing the call to continue.
Example: A business sets up a Call CAPTCHA on its main support line. When someone calls in, they hear a message like: “Please press 7 to continue.”If the caller presses the correct key, the call is routed to the support team. If they fail or do not respond, the call is disconnected or routed to a voicemail or holding queue.
This helps prevent robocalls from clogging up the system and ensures that only legitimate callers get through.
