1. Reject Anonymous Calls Automatically
Many robocalls come up as “anonymous” on your caller ID, while most businesses and human beings come up as identifiable phone numbers. Chances are, you could terminate all anonymous calls without missing anything important.
Depending on your service, you may have access to Anonymous Call Rejection. Try this on your landline. Make sure your caller ID is activated. Enter the magic number *77, and you will hear three beeps. Hang up, and any call that hides its number will be rejected.
This service varies by carrier, and some carriers charge extra. But it’s a helpful tool for scammers or robocallers who slip through the Do Not Call Registry.
