Course Objectives
The Participant will be able to:
Present network
impairments and the challenges to
provide VoIP with acceptable quality
Define other sources for Voice quality
degradation;
Describe the major mechanisms to handle
these problems;
Describe how to test the readiness of
VoIP system;
Describe predictive environment for testing
VoIP
components and system
Present optimization procedure to improve
your VoIP
network performance
Course Overview
In this seminar you will learn the VoIP
challenges, how to provide acceptable QoS and ensure level of service
according well known standards. You will learn the source of network
impairments and voice quality degradation phenomenon; we shall review
some methods for testing VoIP network, and the required testing
tools to implement these tests. We will further discuss the Objective
methods to evaluate the voice quality, analyze results to pinpoint
the problems over the network. Finally we shall discuss about the
possible solutions to overcome these problems to comply with the
customers’ requirements.
Key Benefits
To identify VoIP network impairments and
their sources
Create Predictive environment for reliable
tests (IP
network simulator, Network Impairments recording, setup your
test-lab for reliable results)
To conduct Stress tests for performance
evaluation
To carry out Objective Voice quality testing
methods
(PAMS, PESQ and E-Model)
To elaborate methods of how to pinpoint
Traffic
congestion sources?
