EXAMPLES OF HARDWARE AND SOFTWARE

This section intends to capture the state of the art in IP systems as this book goes to press. It is not an exhaustive catalog of available products, merely examples that represent capabilities and feature sets. Inclusion doesn't indicate an endorsement, and not appearing here means only that a product isn't listed here. When preparing to select a system, you may want to consult various comparisons of telephone systems like the Sourcebook of Hosted and Cloud-Based VoIP and Unified Communications Services at webtorials.com.
