Cisco Voice Systems

This Study Guide explores the different topics that you can expect to see on the Voice CCIE written exam and the voice topics in the CCIE R&S written exam. The assumption is that you already have some background in VoIP and Cisco AVVID (Architecture for Voice Video and Integrated Data).

The tutorial covers the different phones that are deployed with Cisco AVVID, switching architectures and the basics of an end to end IP phone call, Call Manager, Unity, capacity planning and Call Admission Control, common problems such as FXO disconnect and Echo, and briefly touches on Video and SIP.
