Device Pool Configuration


Device pools define sets of common characteristics for devices. The device pool structure supports the separation of user and location information. The device pool now contains only device- and location-related information. The Common Profile window records all the user-oriented information. Ensure that each device is associated with a device pool and with a common profile for user-oriented information.

Use the following topics to configure device pools:

Deleting a Device Pool

This section describes how to delete a device pool from the Cisco Unified CallManager database.

Before You Begin

You cannot delete a device pool if it has any devices that are assigned to it, if it is used for Device Defaults configuration, or if it is the only device pool in the database. If you try to delete a device pool that is in use, a message displays. Before deleting a device pool that is currently in use, you must perform either or both of the following tasks:

Update the devices to assign them to a different device pool. See the "Updating a Phone" section on page 59-10.

Delete the devices that are assigned to the device pool that you want to delete. See the "Deleting a Phone" section on page 59-11.

Procedure


Step 1 Find the device pool by using the procedure in the "Finding a Device Pool" section.

Step 2 From the list of matching records, choose the device pool that you want to delete.

Step 3 Click Delete.

Step 4 When prompted to confirm the delete operation, click OK to delete or click Cancel to cancel the delete operation.

Table 8-1 Device Pool Configuration Settings 

Field Name
Description
Device Pool Settings

Device Pool Name

Enter the name of the new device pool that you are creating.

Cisco Unified CallManager Group

Choose the Cisco Unified CallManager group to assign to devices in this device pool. A Cisco Unified CallManager group specifies a prioritized list of up to three Cisco Unified CallManagers. The first Cisco Unified CallManager in the list serves as the primary Cisco Unified CallManager for that group, and the other members of the group serve as backup Cisco Unified CallManagers for redundancy.

Calling Search Space for Auto-registration

Choose the calling search space to assign to devices in this device pool that auto-registers with Cisco CallManager.

Reverted Call Focus Priority

Choose a clusterwide priority setting for reverted calls invoked by the hold reversion feature. This setting specifies which call type, incoming calls or reverted calls, have priority for user actions, such as going off hook.

Default—If you choose this option, incoming calls have priority.

Highest—If you choose this option, reverted calls have priority.

The Not Selected setting specifies the reverted call focus priority setting for the default device pool at installation. At installation, incoming calls have priority. You cannot choose this setting in Cisco Unified CallManager Administration.

Note This setting applies specifically to hold reverted calls; it does not apply to parked reverted calls.

For more information, refer to Hold Reversion in the Cisco Unified CallManager Features and Services Guide.

Roaming Sensitive Settings

Date/Time Group

Choose the date/time group to assign to devices in this device pool. The date/time group specifies the time zone and the display formats for date and time.

Region

Choose the Cisco Unified CallManager region to assign to devices in this device pool. The Cisco Unified CallManager region settings specify voice codec that can be used for calls within a region and between other regions.

Media Resource Group List

From the drop-down list box, choose a media resource group list. A media resource group list specifies a prioritized list of media resource groups. An application selects the required media resource (for example, a music on hold server, transcoder, or conference bridge) from the available media resource groups according to the priority order that is defined in a media resource group list.

Location

Use locations to implement call admission control in a centralized call-processing system. Call admission control enables you to regulate audio quality and video availability by limiting the amount of bandwidth that is available for audio and video calls over links between the locations.

Network Locale

From the drop-down list box, choose the locale that is associated with phones and gateways. The network locale contains a definition of the tones and cadences that the phones and gateways in the device pool in a specific geographic area use. Make sure that you select a network locale that all of the phones and gateways that use this device pool support.

Note If the user does not choose a network locale, the locale that is specified in the Cisco Unified CallManager clusterwide parameters as Default Network Locale applies.

Note Choose only a network locale that is already installed and supported by the associated devices. The list contains all available network locales for this setting, but not all are necessarily installed. If a device is associated with a network locale that it does not support in the firmware, the device will fail to come up.

SRST Reference

From the drop-down list box, choose a survivable remote site telephony (SRST) reference to assign to devices in this device pool. Choose from the following options:

Disable—If you choose this option, devices in this device pool will not have SRST reference gateways available to them.

Use Default Gateway—If you choose this option, devices in this device pool use the default gateway for SRST.

Existing SRST references—If you choose an SRST reference from the drop-down list, devices in this device pool will use this SRST reference gateway.

Connection Monitor Duration

This setting defines the length of time that the IP phone monitors its connection to Cisco Unified CallManager before it unregisters from SRST and reregisters to Cisco Unified CallManager.

The default value, which specifies 120 seconds, resides in the Connection Monitor Duration enterprise parameter.

Change this setting if you need to disable the connection monitor (by changing the value to zero) or if you want to extend the connection monitor time.

Note When you change the value of the connection monitor duration, it applies only to the device pool that is being updated. All other device pools use the value in their own connection monitor duration fields or use the value that is configured in the enterprise parameter.

For more information, refer to Survivable Remote Site Telephony References in the Cisco Unified CallManager System Guide.

Physical Location

Select the physical location for this device pool. The system uses physical location with the device mobility feature to identify the parameters that relate to a specific geographical location.

Device Mobility Group

Device mobility groups represent the highest level geographic entities in your network and are used to support the device mobility feature.

Device Mobility Related Information

Device Mobility Calling Search Space

Choose the appropriate calling search space to be used as the device calling search space when the device is roaming and in same device mobility group.

AAR Calling Search Space

Choose the appropriate calling search space for the device to use when automated alternate routing (AAR) is performed. The AAR calling search space specifies the collection of route partitions that are searched to determine how to route a collected (originating) number that is otherwise blocked due to insufficient bandwidth.

AAR Group

Choose the automated alternate routing (AAR) group for this device. The AAR group provides the prefix digits that are used to route calls that are otherwise blocked due to insufficient bandwidth. An AAR group setting of None specifies that no rerouting of blocked calls will be attempted.
