Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

Device pools define sets of common characteristics for devices. The device pool structure supports the separation of user and location information. The device pool contains only device- and location-related information. The Common Device Configuration window records all the user-oriented information such as type of softkey template that is used and locale information. Ensure that each device is associated with a device pool and with a common device configuration for user-oriented information.

Device Pool Configuration Settings:

Device Pool Settings

Device Pool Name

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

Cisco Unified Communications Manager Group

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

Calling Search Space for Auto-registration

Choose the calling search space to assign to devices in this device pool that auto-register with Cisco Communications Manager. The calling search space specifies partitions that devices can search when attempting to complete a call.

Reverted Call Focus Priority

Choose a clusterwide priority setting for reverted calls that are 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 Communications Manager Administration.

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

Local Route Group

From the drop-down list box, choose a route group to use as the local route group for the devices in this device pool. Choosing the default value prevents implementation of the Local Route Group feature.

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 Communications Manager region to assign to devices in this device pool. The Cisco Unified Communications Manager 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 is supported by all of the phones and gateways that use this device pool.

Note If the user does not choose a network locale, the locale that is specified in the Cisco Unified Communications Manager 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 time that the IP phone monitors its connection to Cisco Unified Communications Manager before it unregisters from SRST and reregisters to Cisco Unified Communications Manager.

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.

Single Button Barge

This setting determines whether the devices or phone users in this device pool have single-button access for barge and cBarge. From the drop-down list box, choose from the following options:

Off—If you choose this option, the devices in this device pool will have the Single Button Barge/cBarge feature disabled.
Barge—If you choose this option, the devices in this device pool will have the Single Button Barge feature enabled.
CBarge—If you choose this option, the devices in this device pool will have the Single Button cBarge feature enabled.
Default—If you choose this option, the devices in this device pool will use the service parameter setting for the Single Button Barge/cBarge feature.

Join Across Lines

This setting determines whether the Join Across Lines feature is enabled for the devices or phone users in this device pool. From the drop-down list box, choose from the following options:

Off—If you choose this option, the devices in this device pool will have the Join Across Lines feature disabled.
On—If you choose this option, the devices in this device pool will have the Join Across Lines feature enabled.
Default—If you choose this option, the devices in this device pool will use the service parameter setting for the Join Across Lines feature.

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.

Calling Party Transformation CSS

This setting allows you to localize the calling party number on the device. Make sure that the Calling Party Transformation CSS that you choose contains the calling party transformation pattern that you want to assign to this device pool.

Tip Before the call occurs, the device must apply the transformation by using digit analysis. If you configure the Calling Party Transformation CSS as None for the device pool and you check the Use Device Pool Calling Party Transformation CSS check box in the device configuration window, the transformation does not match and does not get applied. Ensure that you configure the Calling Party Transformation Pattern in a non-null partition that is not used for routing.
Called Party Transformation CSS

This setting allows you to localize the called party number on the device. Make sure that the Called Party Transformation CSS that you choose contains the called party transformation pattern that you want to assign to this device pool.

Note If you configure the Called Party Transformation CSS as None, the transformation does not match and does not get applied. Ensure that you configure the Called Party Transformation CSS in a non-null partition that is not used for routing.

Incoming Calling Party Settings

Tip To delete the prefixes in all incoming calling party settings at the same time, click Clear Prefix Settings; to enter the default value for all incoming calling party settings at the same time, click Default Prefix Settings. If the word, Default, displays in the field, Cisco Unified Communications Manager applies the configuration from the incoming calling party number prefix service parameter to the phone. If the field is blank, Cisco Unified Communications Manager does not apply any prefix.

Incoming Calling Party National Number Prefix

Cisco Unified Communications Manager applies the prefix that you enter in this field, which is used to globalize the calling party number, to calling party numbers that use National for the Calling Party Numbering Type. You can enter up to 8 characters, which include digits, the international escape character (+), asterisk (*), or the pound sign (#). Alternatively, you can enter the word, Default, which means that Cisco Unified Communications Manager applies the configuration from the incoming calling party number prefix service parameter to the device. If the field is blank, Cisco Unified Communications Manager does not apply any prefix.

Incoming Calling Party International Number Prefix

Cisco Unified Communications Manager applies the prefix that you enter in this field, which is used to globalize the calling party number, to calling party numbers that use International for the Calling Party Numbering Type. Alternatively, you can enter the word, Default, which means that Cisco Unified Communications Manager applies the configuration from the incoming calling party number prefix service parameter to the device. If the field is blank, Cisco Unified Communications Manager does not apply any prefix.

Incoming Calling Party Unknown Number Prefix

Cisco Unified Communications Manager applies the prefix that you enter in this field, which is used to globalize the calling party number, to calling party numbers that use Unknown for the Calling Party Numbering Type. Alternatively, you can enter the word, Default, which means that Cisco Unified Communications Manager applies the configuration from the incoming calling party number prefix service parameter to the device. If the field is blank, Cisco Unified Communications Manager does not apply any prefix.

Incoming Calling Party Subscriber Number Prefix

Cisco Unified Communications Manager applies the prefix that you enter in this field, which is used to globalize the calling party number, to calling party numbers that use Subscriber for the Calling Party Numbering Type. Alternatively, you can enter the word, Default, which means that Cisco Unified Communications Manager applies the configuration from the incoming calling party number prefix service parameter to the device. If the field is blank, Cisco Unified Communications Manager does not apply any prefix.
