Introduction

To help determine your network’s readiness for VoIP, 8x8 provides our customers with three

VoIP readiness tools . This document provides detailed information on the 8x8 Network

Monitoring Tool which monitors your network for hours or days to generate a report on

latency, jitter, and packet loss over a sustained time period .

We generally recommend that you start with our first two VoIP readiness tools to get an

instant snapshot of your Internet connection performance and your network attributes

before using the Network Monitoring Tool .

Overview of 8x8 VoIP Readiness Tools

Test #1: VoIP Quality and Connectivity speed

Purpose: Tests your Internet connection to determine how many concurrent VoIP calls it can

support, your upload and download speed, and quality of service . The results of this test may

vary based on what time of day you run it and other activity on your network . This test is a

good way to prequalify your network for VoIP phone service .

Location: http://www .8x8 .com/Resources/Tools/VoIPTest .aspx

Test #2: Network Diagnostic Tool

Purpose: Takes a snapshot of the following network attributes that affect 8x8 VoIP call

quality:

•DNS service

•Network path characteristics

•NAT/Firewall/Router characteristics

•Packet loss rates

• Jitter levels (changes in network traffic delivery times)

•Round trip network delay (latency) between your network and the 8x8 servers

If you run the Network Diagnostic Tool and the report says OK on all parameters, but you still

have call quality issues, then the 8x8 Network Monitoring Tool may help identify the cause

of network issues .

Test #3: The 8x8 Network Monitoring Tool

frame of one to several days . It can help uncover time-of-day events which are missed in the

prior tests .

Note: You must be an 8x8 customer or qualified prospective customer to run this test .

The Network Monitoring Tool

The 8x8 Network Monitoring Tool helps you measure your network performance over

time, relative to 8x8 Virtual Office telephone service . It measures latency, packet loss

and jitter over your network . You download and install the application on a Microsoft

Windows computer .

This tool is only for use by 8x8 customers or qualified prospective customers . You will need

to call 8x8 Support to obtain a license key to activate the Network Monitoring Tool.

Getting Accurate Results

To obtain the most meaningful results:

1 . Make sure that the Windows machine running the tests is only running the 8x8 Network

Monitoring Tool . Running other Microsoft Windows applications simultaneously may

cause inaccurate results .

2 . Plan to test your network for an extended period of time as indicated by your 8x8

support representative . The time frame can vary from several hours to one month .

3 . Save the test results and email them to your 8x8 support representative .

Installation

The 8x8 Network Monitoring Tool runs on your Microsoft Windows XP, Vista, or 7 operating

system and must be connected to the same logical LAN (Local Area Network) as the 8x8

IP phone devices . Be sure the test computer is connected to your network with an

Ethernet cable .

Operating the tool uses approximately 34MB of RAM and utilizes less than 1% of computer

CPU processing power (based on a dual-core 2 .53GHz laptop computer) .
