Overview: Reliability is the most critical aspect of a business phone system. IP telephony systems will deliver differing service levels because their architecture is fundamentally different. Ironically, optimal architecture and design does not only deliver high reliability, but also produces a system that is easy to use and manage.
This whitepaper defines reliability and availability and then compares the approaches of various IP telephony vendors take to ensure high availability. You will see how the underlying system design and architecture dictate the type of redundancy that can be deployed to increase reliability.
