Configure IP Phones

You can use the NNMi Nortel IP Phone Configuration form to configure the following:

• The range of IP Phone extensions to be excluded from monitoring
• The list of IP Phones to be included for generating incidents at the Registration State Change

Specifying the Range of Extensions for Nortel Phones to be Excluded from Monitoring

You can specify the range of extensions for phones to be excluded from being monitored for Nortel IP telephony network. After you specify the range of extensions for Nortel, the NNMi stops monitoring these phones and does not discover these phones in the subsequent discovery cycles

To specify the range of extensions for Nortel phones to be excluded, follow these steps:

1. On the NNMi Nortel Configuration console, click IP Phone Configuration. The NNMi Nortel IP Phone Configuration form opens.
2. In the Exclusion Configuration > Add/Modify IP Phone Exclusion Filter section, specify the required details in the fields provided on the page. The following table describes the fields on the page:

   Field Name	Description
   CS IP Address	Indicates the IP address of the Call Server for which you want to specify the list of phones to be excluded.
   Filter	Indicates the IP phones extension range to be excluded. To specify the range of phones to be excluded, follow these points: Use the hyphen (-) to specify a range of extensions to be excluded. For example, if you want to exclude extensions from 8000 to 8005, you can specify as 8000-8005 in the Filter field. Use asterisk (*), the wildcard character, to specify a set of extensions. For example, if you want to exclude all the extensions that start with 8, you can specify as 8* in the Filter field. Use question mark (?), the wildcard character, to specify extensions that contain specific numerals at specific locations in the extension. For example, if you want to exclude all the extensions that end with 00, you can specify as ???00 in the Filter field.

3. Click Add/Modify. The configured call servers for which you want to exclude the list of phones are listed in the Current Configurations section.

To modify a specified range of Nortel extensions to be excluded, follow these steps:

1. On the NNMi IP Phone Exclusion Configuration form (for Nortel Configuration), from the Current Configurations section, select the configuration that want to modify.
2. Click Modify.
3. In the Add/Modify IP Phone Exclusion Filter section, make the required changes.
4. Click Add/Modify. The modified configuration is listed in the Current Configurations section.

To delete a specified range of Nortel extensions to be excluded, follow these steps:

1. On the NNMi IP Phone Exclusion Configuration form (for Nortel Configuration), from the Current Configurations section, select the configuration that want to delete.
2. Click Delete. The selected configuration is deleted from the Current Configurations section.

Specifying the List of IP Phones for Registration State Change Incident Generation

You can specify a list of IP phones for which the registration state change incident must be generated. You can specify a range of IP phones based on the Call Server that includes the IP phones.

To specify the list of IP phones for registration state change incident generation, follow these steps:

1. From the Workspaces navigation pane, click Configuration > iSPI for IP Telephony Configuration > Nortel Configuration. The NNMi configuration form opens.
2. Click IP Phone Configuration. The NNMi Nortel IP Phone Configuration form opens.
3. In the Inclusion Configuration > Add/Modify Filters for IP Phones for which Registration State Change Incidents are to be Generated section, specify the required details in the fields provided on the page. The following table describes the fields on the page:

   Field Name	Description
   CS IP Address	Indicates the IP address of the Call Server in the field. This IP address specifies the Call Server IP address that includes the list of phones for which the registration state change incident must be generated .
   Filter	Indicates the extension range to be included. For more information, see the Specifying the Range of Extensions for Nortel Phones to be Excluded from Monitoring.

4. Click Add/Modify. The Current Configurations section lists the configured Call Servers for which you want to generate the incident for registration state changes. You can select a CS IP address from the list and click Modify to modify the existing configuration. To delete an existing configuration, you can select a CS IP Address, and click Delete.

Configure Polling

You can use the NNMi Nortel Polling Configuration form to enable polling and set intervals for the pollers that are grouped based on the Call Managers to be polled.

To configure the polling of a Call Manager, follow these steps:

1. On the NNMi Nortel Configuration console, click Polling Configuration. The NNMi Nortel Polling Configuration form opens.
2. In the Call Manager Specific Polling Configuration section, specify the required details in the fields provided on the page. The following table describes the fields on the page:

   Field Name	Description
   QOS Zones Monitoring	Allows you to configure the continuous polling of the various QOS-related measurements in the Nortel QOS Zones. The available options are as follows: Enable Polling: Select this check box to enable incident generation based on the values of the QOS metrics that are configured with the Nortel Signaling Server. Interval: Indicates the interval (in seconds) to poll the Nortel Signaling Sever to collect the details of QOS metrics. The default value is 300 seconds.
   IP Phones Registration State Monitoring	Allows you to configure the continuous polling of the registration state of the Nortel IP Phones on the network. The available options are as follows: Enable Polling: Select this check box to enable the registration state of the Nortel IP Phones. Interval: Indicates the interval (in seconds) to poll the registration state of the Nortel IP Phones. The default value is 1800 seconds.
