Advanced Call Center is a full-featured yet easy-to-use answering machine software for your voice modem. All necessary functions are supported: Caller ID lets you see and hear who's calling via screen pop-ups, distinctive rings and caller's name announcement with speech synthesis. "Black" and "white" list functions filter calls based on caller database, call origin and other parameters. You can map personalized greetings to callers, organize information in phone books and record conversations. Advanced features include pager notification, sending call details and voice messages over e-mail, and starting an external fax program when an incoming fax call is recognized. Tightly integrating voice modem with the sound card, ACC offers a feature that leading competitors do not - real time voice transfer from telephone line to PC sound system, so you don't need an extra speaker attached to the modem! Runs as a tray application when idle, uses minimum system resources, and automatically frees the modem for an Internet connection. Lastly, ACC looks just as great as it works!
