About VoIP Monitoring Manager

VoIP Monitoring Manager is a Voice over IP (VoIP) Quality of Service (QoS) monitoring tool. It

enables you to monitor and review the quality of a call on an AVAYA™ VoIP network. Using the

VoIP Monitoring Manager, you can view the Jitter, Round Trip Time (RTT) and Packet Loss

experienced at the endpoints and during a session. The QoS data displays currently active

endpoints or for endpoints active in the past. With this information, you can begin to troubleshoot

and isolate problems.

If you are new to using the VoIP Monitoring Manager, the following information explains what you

can do with this tool.

Search for Endpoints

You search endpoints active from some time in the past or within a date range. The Advanced

Search options enable you to narrow your search to match phone numbers, SIP user names,

network addresses, or QoS level.

View Reports

Once you have completed your search, you can view a summary or a detailed report. The reports

display the QoS data for selected endpoints. This is particularly useful for monitoring Gateways or

locating problems at a particular endpoint. You can also view a report for endpoints involved in a

session. This will assist with determining problems that occur between two endpoints or in an

isolated area of the network.

Generate Automatic Alarms

You can generate SNMP Traps/Alarms , which enables the VoIP Monitoring Manager to alert you

when the Jitter, Round Trip Time or Packet Loss reaches certain levels. This assists you to

routinely monitor the network, and troubleshoot problems.

About VoIP Monitoring Manager Client

The VoIP Monitoring Manager (VMM) Client provides the graphical user interface (GUI) for VoIP

Monitoring Manager. The VMM Client does not communicate with the VMM RTCP Monitor and

does not use SNMP. The data that is displayed is gathered from the VoIP Monitoring Manager

(VMM) Server.

The VMM Client may be installed on the same machine as the VMM Server, or it may be installed

on another machine on the network. It is possible for the VMM Server and the VMM Client to

communicate over a dial-up connection.

About VoIP Monitoring Manager Web Client

The VoIP Monitoring Manager (VMM) Client can run as a web application in a browser. This is

useful if you only have the VMM Server installed.

The VMM Server needs to be running a web server. If you purchased Avaya Integrated

Management, the Apache web server will already be installed and running. If you choose to run

the Apache web server, the VMM installation will assist with configuration. The machine running

the VMM Web Client needs to have the Sun Java Plug-in installed to run the Web Client.

Configure the web server to publish the file to the following default install path:

C:\Program Files\Avaya\VoIP Monitoring Manager\jars\ClientApplet.htm

If you run the web client you will not have access to all the functionality available in the

application. This includes features such as copy and connect to a new server. For more

information see Starting VoIP Monitoring Manager Web Client.

About VoIP Monitoring Manager Server

The VoIP Monitoring Manager Server acts as a proxy between the VoIP Monitoring Manager

Client and the VoIP Monitoring Manager RTCP Monitor. The main purpose of the VoIP Monitoring

Manager Server is to reduce the amount of traffic to the VoIP Monitoring Manager Client by

performing large data downloads and extensive processing of the MIB data stored on the RTCP

Monitor. The VoIP Monitoring Manager Server can reside on the same PC as the RTCP Monitor.

Components of VoIP Monitoring Manager

The VoIP Monitoring Manager (VMM) application comprises the VMM RTCP Monitor and the

VMM Server, which accepts connections from the VMM Client. If you only have the VMM Server

installed, you can run VMM Client as a web client.

To ensure it will run correctly, you will need to have configured the Switch Administration Forms,

have a Windows SNMP Agent installed on the Server and the Monitoring Manager Server needs

to be installed onto the network.

The components and their relationship are described in more detail in the following links:

 VoIP Monitoring Manager Server

 VoIP Monitoring Manager RTCP Monitor

 VoIP Monitoring Manager Client

 VoIP Monitoring Manager Web Client

 Database

About Licenses

VoIP Monitoring Manager requires licenses that you must purchase from Avaya. You can

purchase these licenses in sets of 2000 phone endpoints and 40 media gateways. The Avaya

licenses are managed by the WebLM server, which is provided with VoIP Monitoring Manager.

By selecting Help>About in the VMM Server or the VMM Client, you can view the following

information:

 the number of licenses purchased

 the number of phones at the local server. This number represents the phones that

reported to VMM in the last 28 days. This number will increase if you move phones (for

example, change extensions or IP addresses). In this case, these phones appear to be

new endpoints to VMM. Since there is a 30-day grace period, this will not be a problem.

 the number of phones at the local server that exceed the license (that is, the number of

phones that are unlicensed). If greater than zero, this number is displayed in red. This

can occur if you have only one monitor connected to the WebLM License Server, and you

have more phones stored in the database than licenses purchased.

 the number of media gateways at the local server. This number represents the media

gateways that reported to VMM in the last 28 days.

 the number of media gateways at the local server that exceed the license (that is, the

number of media gateways that are unlicensed). If greater than zero, this number is

displayed in red. This can occur if you have only one monitor connected to the WebLM

License Server, and you have more media gateways stored in the database than licenses

purchased.

Each VMM RTCP monitor periodically checks the number of endpoints it knows about and

requests/renews the licenses for them. If there is more than one RTCP monitor and the total

number of endpoints known exceeds the number of licenses, the RTCP monitor that requests

licenses first will get its licenses. The RTCP monitor that requests licenses last will be denied

licenses. If you enter the 30-day grace period because license limits were exceeded, the About

dialog box will appear every time the VMM Server and VMM Client are started. If you exceed the

30-day grace period, VoIP Monitoring Manager stops collecting RTCP data.

Avaya provides a 90-day trial version of VoIP Monitoring Manager. After 90 days, VoIP

Monitoring Manager stops collecting RTCP data. You have the option of purchasing the VoIP

Monitoring Manager license key from Avaya to fully activate the VoIP Monitoring Manager beyond

the 90-day trial period. When a license key is purchased, an instance of WebLM License Server

is required to manage the license key.

Contact your authorized Avaya Sales Representative to purchase additional VMM licenses.
