Mô tả: Reliability is the most critical aspect of a business phone system: You pick up the phone and you get a dial tone, period. ShoreTel delivers IP (Internet Protocol) telephony systems with unmatched reliability, using an approach that is fundamentally different from that of any other IP PBX supplier in the world. ShoreTel’s architecture and design not only deliver high reliability, but do so in a very simple and cost-effective manner. This paper describes ShoreTel’s unique approach to providing extremely reliable VoIP.

We start by defining reliability and availability, and then compare the approaches ShoreTel and other IP telephony vendors take to ensure high availability of their IP PBX hardware. You will see how the underlying system design and architecture dictate the type of redundancy that can be deployed to increase reliability, and why ShoreTel’s n+1 redundancy is so much simpler and more cost-effective than the 1:1 redundancy used by other systems. The paper also addresses the reliability of the underlying data network and the challenges of implementing a virtually always available voice system on an infrastructure that has a much lower availability rating.

No enterprise voice system today is without such applications as auto-attendant and voice mail, so we examine application reliability and the need to hold applications to the same reliability and availability standards as the voice system hardware. Finally, we finish by looking at soft reliability issues—the impact that software problems, administrative and maintenance activities, and network quality can have on voice system availability.
