About this Course

Implementing Cisco Voice Communications and QoS (CVOICE) v8.0 teaches learners about voice gateways, characteristics of VoIP call legs, dial plans and their implementation, basic implementation of IP phones in Cisco Unified Communications Manager Express environment, and essential information about gatekeepers and Cisco Unified Border Element. The course provides the learners with voice-related quality of service (QoS) mechanisms that are required in Cisco Unified Communications networks.
