Who's Calling - Version 4.1.2 Who's Calling is a Speaking Caller ID utility with a big difference. Not only will it keep a log of your incoming caller ID calls, but it can also dial your telco's last caller number and record the spoken message on that line. Then the call is logged and available for replay at any time. You don`t even need to subscribe to your telco's caller ID service to use this software. If you do have caller ID and your caller is in your address book, then their name or an announcement will also be spoken when they call. You can block an unlimited amount of telephone numbers and have others emailed to you when they call for your information. There is also a speaking clock which can tell you the time at a user defined interval. The only requirements that you need are a Voice compatible modem, and optionally an email account. Give this software a try today, prepare to be impressed.
