Changing the VoIP Monitoring Manager Server Settings

Issue 6 June 2005 23

Changing the VoIP Monitoring Manager Server Settings

Data that is reported depends on settings that are made in the server. The default settings are a

good starting point, but are intended only as a guide. Changing some settings can help you

obtain better reports. Over time, you will be able to fine-tune the server settings in order to

highlight abnormal operation for your specific environment.

Generating Traps

Rules are set to generate traps that notify you when the VoIP network QoS parameters have

reached unacceptable levels. Rules are defined in the Trap Threshold Settings dialog box,

which provides a tab for Call Traps and a tab for System and Terminal Traps. To open the Trap

Threshold Settings dialog box, from the VoIP Monitoring Manager Server window, select Edit >

Trap Settings.

More than one rule can be set for each type of trap, and each rule can be made up of more than

one condition. When a rule has more than one condition, all conditions must be satisfied before

a trap is sent.

The RTCP Monitor generates a trap to a pre-configured Trap Manager when the RTCP Monitor

experiences the conditions defined. The Trap Manager is generally configured to be the

Gateway Alarm Manager (GAM) or Network Alarm Manager (NAM) but any Trap Manager

application can be used. Traps can be set for Calls (Sessions), Systems (Networks), and

Terminals (endpoint).

VoIP Monitoring Manager creates traps based on two sets of rules:

● Call Traps

If a specified condition occurs anywhere in the system, a trap is sent immediately.

● System Traps

The specified condition must occur a specified number of times before a trap is sent. This is

based on an accumulation of warnings from the entire system.

Recommended Trap Settings

Values that you use to trigger traps must be fine-tuned to suit your environment. Appropriate

settings may vary greatly from one country to another.

The default settings that are in place when VoIP Monitoring Manger is installed are a useful

starting point. These settings are based on an environment with high-quality

telecommunications facilities. For example, in this environment it is reasonable to expect RTT of

less than 300. Recommended trap settings are provided in Table 3
