Call Shield is an anti-telemarketing telephone program that prevents unwanted calls by prompting all callers with a Personal Identification Number (PIN). Additionally, Call Shield blocks charities, surveys, prank calls, and wrong phone numbers - things the national do-not-call list can't stop. Also, Call Shield automatically removes your number from automated dialing computers - just like those expensive devices seen on TV.
