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 .

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
Purpose: Measures latency, packet loss and jitter on your network over a sustained time
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.
Please consult your 8x8 support representative to review and interpret results .
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) .
Download the application from http://sims .8x8 .com/GetDocument .aspx?docid=710581 and
