Who's Calling turns your PC into a high-tech CallerID (CID) box with advanced features. It even works for users who don't have CID services by dialing out to a phone company service and getting the caller information. It's easy to install and use, working with CID service to audibly announce incoming calls by speaking the number, record caller information, block unwanted calls, email call notifications, and more. You can create a list of callers to block. When a blocked number is received, the phone is simply disconnected. Recorded calls can be added to a phone book then selected and automatically dialed to return phone calls. Complete online help makes it simple to tweak settings and have Who's Calling running properly in just a few minutes. Whos Calling works with most TAPI and non TAPI Caller ID modems and also Rochelle Caller ID plugs.
