Question: Do you know of a service that can force unknown callers to identify themselves before connecting me?

If you're looking for a service to force unknown callers to identify themselves before connecting, TrapCall is a great option. It uses patented technology to unmask blocked calls and requires unknown callers to reveal themselves before connecting using its Privacy Lock feature. This service works with major US carriers and offers various plans, including a free 7-day trial.

Another effective tool is Whoscall, which offers real-time caller ID and automated blocking of spam calls. It uses AI to screen out suspicious SMS and data leaks, and it's available on iOS and Android. The app provides a 2.6 billion phone number database for identification and offers a Premium version with additional features like auto-updating of the number database and no ads.

For a comprehensive suite of solutions, consider Hiya. It includes Hiya Connect for businesses to show their caller ID on outbound calls, Hiya Protect for advanced spam protection, and the consumer app Hiya App for identifying and blocking unwanted calls. Hiya uses Adaptive AI for spam protection and offers call analytics to improve the overall voice experience.
