Cisco CVOICE 8.0: Introduction to Voice Gateways

This course is included in our On-demand training solution.


Cisco voice gateway relays high quality voice and fax traffic across an IP network. This course describes the operational modes of a voice gateway and how it fits in the Cisco Unified Communications architecture. It explains the voice gateway functions in each Cisco Unified Communications deployment model and the call legs that are associated with each operational mode.
A primary function of the Cisco Unified Communications gateways is to route calls. The process of call routing includes the processing of incoming and outgoing call legs. This course also describes how call legs are created when inbound and outbound dial peers are matched. It provides details about the dial-peer matching process and explains the direct inward dialing (DID) feature.
