Interactive Voice Response offers free caller ID software for download on its website. The program alerts computer users of incoming calls with speech or a melody. The software also sends incoming calls to the computer user's email.
The caller ID alerts the computer user of who is calling with a popup window near the PC's taskbar. Users can customize the program to only alert them if an important person calls, so they can easily block telemarketers and unknown numbers. The program disconnects the phone immediately when the user sets up an address book and then someone from the user's blocked list calls.
