VoIP Architectures

This document serves as an implementation guide for Voice over IP (VoIP) networks based on Cisco AVVID (Architecture for Voice, Video and Integrated Data). The goal of this document is to provide a blueprint for implementing the end-to-end Quality of Service (QoS) that is required for successful deployment of Cisco AVVID solutions in today’s enterprise environment. This document cannot examine all the possible QoS configurations available for all Cisco AVVID products.
