In order to provide sufficient bandwidth for incoming and outgoing calls, a collaboration engineer is required to know how the human voice gets converted into an Internet Protocol (IP) signal. In this course, you'll explore voice and video codecs in a Voice over Internet Protocol (VoIP) network and examine bandwidth management. You’ll begin by identifying the process of encoding and decoding voice using codecs, different levels of compressions applied on IP signals, and how these IP signals get transmitted over an IP network. You’ll also outline how to determine bandwidth requirements for specific codecs. Finally, you’ll investigate bandwidth calculation and management techniques and demonstrate call admission control (CAC) configuration using Cisco Unified Communication Manager (UCM). This course is a part of a collection of courses that will prepare you for the 350-801: Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) certification exam.
