Cisco GWGK 2.0 Instructor Series: Limiting Calls w/ COR & Gateway Features

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


This course is part of Skillsoft's Instructor Series, technical courses presented in spontaneous lecture-style by subject matter experts. This is 4 of 6 of the Implementing Cisco Voice Gateways and Gatekeepers (GWGK) 2.0 series. This is an advanced course on implementing Cisco Voice Gateways and Gatekeepers in Enterprise or Service Provider environments. The goal of the course is to provide students with information and practice activities to prepare them to install, configure, monitor, and troubleshoot Cisco voice gateways and gatekeepers in enterprise installations in accord with the recommendations of Cisco's Solution Reference Network Design (SRND) for IP Telephony guides. Given a voice over IP design, the implementer will select an appropriate deployment model, correctly configure the gateways and gatekeepers, implement dial plans, and decide how to implement the most commonly offered service provider or managed services applications, features, or implementation requirements.
