Call Whisper is a neat new feature that lets you know instantly when your 0800, 0845 and 0844 numbers are being used.When a customer rings your 0800, 0845, 0871 or 0844 number they will hear the normal ringing tone but, when you pick up the phone to answer the call you will instantly hear a brief message saying, for example, "this is call from your 0800 number."If you have an 08 prefix number pointed at your mobile this would be a great way to distinguish between personal or business calls so that you didn't answer the phone with "hello" but a business type greeting ie "thanking you for calling ABC Limited. How may I help you?"If you use multiple 08 prefix numbers to monitor and track each and every one of your adverts then call whisper will help too. For example we can programme a message such as “this is a call from the 0800 number in the Leeds Yellow Pages.
