Cisco IP Telephony Design Specialist Certification

Designed for systems engineers, the Cisco IP Telephony Design Specialist certification covers the technical issues related to the design of voice over data networks including in-depth coverage of IOS-based and Call Manager-based voice network designs, the Cisco methodology for implementing voice over data networks, and Deploying Quality of Service (DQoS). Deploying Cisco QoS provides a methodology for identifying the characteristics of future types of traffic and applies QoS design criteria to enable successful enterprise network tuning in IP phone environments.
