Active CallerID is a powerful full-featured Caller ID detection software that will turn your PC into an advanced Caller ID device. It uses your MODEM and Caller ID service provided by your local phone company in order to identify who's calling.

Active CallerID has its own built-in Address Book that will keep your contacts in one place where they will always be easily available. It allows you to associate a ring audio file(.wav file) to per contact.

Do you want to know who called a few weeks ago? Active CallerID Call List will log and save all your incoming call information. The program will manage all incoming calls for you, even if you're not around. You can review your calls anytime you want to.
