Course Description
This course provides you with the information you need to develop IP telephony gateway or media server applications using NMS Communications' Fusion development platform. Lectures provide a fundamental understanding of Fusion features and functionality, including the MGCP API used to perform IP call control. Hands-on exercises include installing, configuring and testing the Fusion software as well as building and tearing down media connections, issuing commands to modify parameters and using queries to assess endpoint and channel filter states. A new module has been added that covers troubleshooting tools and techniques.

Additional Notes
This information applies to all 7 modules described below. This course can be customized to include a subset of the modules.
Modules
Introduction to Fusion
This module describes the four major components of the Fusion development platform: the CG 6000C board, Natural Access Core software, Media Stream Processing Protocol (MSPP) Service and third party products used for IP signaling. Endpoints, channels, connections and filters are introduced to explain conceptually how Fusion transforms and manages the data flow.
Installation and Configuration
This module explains how to configure and customize your system. Demonstration programs used to verify that the board and software are installed correctly are presented. Hands-on practice includes installing and configuring the Fusion software and verifying the installation.
MSPP Service — API
This module describes the functions used to create, enable, connect, disconnect, disable and destroy endpoints and channels. It also describes the functions used to command and query channel filters. Hands-on practice includes writing a program to create, enable, connect, disable and destroy endpoints and channels. The exercise also includes sending commands and queries to filters.
MSPP Service — Voice and Switch Filters
This module describes the features and functionality of the MSPP voice and switch filters (inputs, outputs, parameter settings and tradeoffs to achieve voice quality requirements). Both endpoint filters (DS0, RTP and TPKT) and channel filters (encoder, decoder, jitter, and switch) are discussed in detail.
Troubleshooting Voice
This module explains how to troubleshoot NMS board configuration problems, nework and switch connectivity problems and IP settings. A step-by-step troubleshooting methodology is presented and supporting tools and demonstration programs are introduced. Hands-on exercises provide practice troubleshooting a variety of problems.
MSPP Service — Fax Filters
This module describes the features and functionality of the MSPP T38UDP endpoint filter and the T.38 Fax Relay channel filter (inputs, outputs, parameter settings and tradeoffs to achieve fax quality requirements). Voice-to-fax switchover techniques are also discussed.
MCGP API
This module introduces Media Gateway Control Protocol (MGCP) concepts such as call agents, gateways, event packages, etc. and describes how the Fusion MGCP service interacts with call agents and other Natural Access services. Hands-on practice includes modifying an existing MGCP application.
