Telecommunications engineers will need to ensure the quality of audio and video. Understanding the various QoS tools is helpful when determining implementation in the network. In this course, you will learn the various options for implementation of QoS on your network interfaces at layer 2 and layer 3.

Target Audience
Today's IT Telecommunications Engineer working with the Cisco Unified Communications Manager must understand the basic foundation of the call agent. If you are interested in persuing CCNP collaboration, this course is necessary. Today there is a need for dedicated individuals focused on the Collaboration solution and Cisco recommends a Chief Collaboration Officer position for focus on voice and video technologies. Anyone interested in implementing or supporting the Cisco IP Telephony and Video solutions should also consider this course.
