Introduction
It’s safe to say Internet Protocol (IP) telephony has arrived as a feasible communications technology for business. And for good reason. Now that the telecom industry has had time to refine it and more organizations are deploying it, IP telephony is delivering on its claims of reducing calling costs, simplifying administration, and providing greater communications flexibility with software applications taking the place of traditional hardware systems. IT chiefs and corporate level decision-makers also are looking more closely at IP telephony as voice quality continues to improve, and as organizations that use IP continue to consistently reach the “Five ’s” level of reliability with 99.999% system uptimes.
