A new and improved apparatus is disclosed for screening telephone calls. The apparatus would be a device which would be electronically connected to a phone line in between a telephone and a wall jack. The apparatus would have a programmable numerical key pad and also would have a top-mounted speaker. The apparatus would serve as an interceptor of telephone calls. Once another person would call a person who had the present invention, the other person would have to enter a 2/3 code within ten to twelve seconds, or they would be cut off. If the other person entered the correct code, the present invention would play an eternal melody note that would indicate a welcome call.
