Any service or technology that shakes up the status quo is bound to have its own set of critics and VoIP phone systems are no exception. There are enough doubters around who question whether businesses can indeed depend on a VoIP phone system. The primary cause for doubt? That such a phone system is entirely dependent on the Internet, and if the Internet connection goes down, there is no phone system to talk about. Can a business really afford such a risk?

Certainly not, but the question in many ways is representative of the "half-empty, half-full" syndrome. How does one really want to view it? Negatively, and saying that the risks are simply too much to use a VoIP phone system, or positively, saying that there is some dependence on the Internet, but Internet connectivity is continuously improving worldwide and therefore, the reliability of a VoIP service is bound to improve as well? Are traditional phone systems have absolutely no downtime? Are they immune to occasional breakdowns? If not, and we have accepted that, there is no reason why a VoIP phone system cannot gain that same acceptance.
