Voice mail is so easy and so cheap. In fact, voice mail is free with a cellular phone service, and may even be offered free by various online retailers. Yet, cheap or free service is not always the best quality of service that you want. If you are a businessperson trying to establish positive relations with your customer base, then you want only to deliver the best quality service selling the best products. Unfortunately, voice mail is a weak substitute for a professional telephone answering service.
