Description: Picture Caller ID identifies callers before you answer the phone. Call Blocking enables effective telemarketer call block by cutting off black-listed numbers, such as the numbers that are blocked, out-of-area, or unidentified. Picture Caller ID lets you screen your calls using text-to-speech to announce the caller's name and number, so you only answer the call when you want to. It sits silently in the system tray, notifying you when a call comes.
