Cisco CallManager Fundamentals provides examples and reference information about Cisco CallManager, the call processing component of the Cisco AVVID (Architecture for Voice, Video, and Integrated Data) IP Telephony solution. Cisco CallManager Fundamentals uses examples and architectural descriptions to explain how CallManager processes calls. The book details the inner workings of Cisco CallManager so that those responsible for designing and maintaining a Voice over IP (VoIP) solution from Cisco Systems can understand the role each component plays and how they interrelate. Detailed information is provided about North American and International dial plans, trunk and station devices, media resources, managing and monitoring CallManager, and call detail records. A list of features and Cisco solutions that integrate with CallManager is also provided.
