With our 24x7 Live Answering Service there is no need for you to change your existing phone number if you are an established business. During the FREE 7 Day Trial setup, which takes 5 minutes, you allocate your business a unique local telephone number (e.g. 02, 03, 07, 08 etc). This is the number we know your business by, which allows us to answer your calls exactly as you require. If you are a startup business simply use your allocated number as your main business phone number!
