It works on your existing phone number to let you receive and respond to phone calls while online. It comes complete with Caller ID and your own private voicemail.

As calls come in, this delivers them to your desktop and tells you who's calling. You may then go offline and take the call, type a text-to-speech reply that is read to the caller, send the call to voicemail, or reject it.

The voicemail operates as a regular telephone company message center. You can check stored voice messages using either the telephone or the Web.

Microsoft Outlook Contacts can be imported into the address book, and a call log stores all callers' phone numbers.

This works with all dial-up ISPs, cable modem, ISDN and DSL connections. Sometimes it does not operate from behind corporate firewalls. It works with Netscape 4.0 and above, Internet Explorer 4.0 and 5.0, and America Online 4.0 and 5.0. This is currently only available for use in the United States.
