If you have an 0800, 0844, 0845 or local phone number pointing to your mobile phone or landline, chances are it is for business purposes, whereas your mobile or landline number is probably for personal use. However, when your phone rings, you don’t know if it is going to be a call to your business number or a call to your personal number. Therefore, you don’t know how to answer the phone.
If you have more than one business, and have numbers for those businesses pointing to your phone, then again you won’t know what business the person calling is expecting to be at the end of the phone, and so won’t know how to answer the call.
A call whisper solves all of these problems – a short recorded message plays you a message of your choice with each call, so you know exactly what number people are calling in on.
