"Voice over Internet Protocol (VoIP) generates a tremendous amount of excitement these days. The cost savings associated with VoIP are potentially tremendous, regardless of whether you lease service from a provider or implement your own services. Imagine how much your boss would appreciate you, if you could demonstrate how to completely eliminate monthly long distance charges between your company’s two sites that are in different states; how grateful he would be if you could eliminate all the charges he has to pay for internal conference calls through whatever service he now uses; or how much you will be worth to him, if you can eliminate all the costs associated with your company's current voice mail system."
