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.

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.

Softkey Template

From the drop-down list box, choose the softkey template that is associated with the devices in the device pool.

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.

Calling Search Space for Auto-registration

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

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.

Network Hold MOH Audio Source

Choose the audio source to use for music on hold (MOH) when the network initiates a hold action.

User Hold MOH Audio Source

Choose the audio source to use for music on hold (MOH) when a user initiates a hold action.

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 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 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.

User Locale

From the drop-down list box, choose the locale that is associated with the phones and gateways in the device pool. The user locale identifies a set of detailed information to support users, including language and font.

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

Connection Monitor Duration

This setting defines the amount of time that the IP phone monitors its connection to Cisco Unified CallManager before it unregisters from SRST and re-registers 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.

Multilevel Precedence and Preemption (MLPP) Information

MLPP Indication

This setting specifies whether devices in the device pool that are capable of playing precedence tones will use the capability when the devices place an MLPP precedence call.

From the drop-down list box, choose a setting to assign to the devices in this device pool from the following options:

Default—This device pool inherits its MLPP Indication setting from the MLPP Indication Status enterprise parameter.

Off—Devices in this device pool do not handle nor process indication of an MLPP precedence call.

On—Devices in this device pool do handle and process indication of an MLPP precedence call.

Note Do not configure a device pool with the following combination of settings: MLPP Indication is set to Off or Default (when default is Off) while MLPP Preemption is set to Forceful.

Note Turning on MLPP Indication (at the enterprise parameter, device pool, or device level) disables normal Ring Setting behavior for the lines on a device, unless MLPP Indication is turned off (overridden) for the device.

MLPP Preemption

This setting specifies whether devices in the device pool that are capable of preempting calls in progress will use the capability when the devices place an MLPP precedence call.

From the drop-down list box, choose a setting to assign to the devices in this device pool from the following options:

Default—This device pool inherits its MLPP Preemption setting from the MLPP Preemption Setting enterprise parameter.

Disabled—Devices in this device pool do not allow preemption of lower-precedence calls to take place when necessary for completion of higher-precedence calls.

Forceful—Devices in this device pool allow preemption of lower-precedence calls to take place when necessary for completion of higher-precedence calls.

Note Do not configure a device pool with the following combination of settings: MLPP Indication is set to Off or Default (when default is Off) while MLPP Preemption is set to Forceful.

MLPP Domain

Enter a hexadecimal value between 0 and FFFFFF for the MLPP domain that is associated with this device pool. If you leave this field blank, this device pool inherits its MLPP domain from the value set for the MLPP Domain Identifier enterprise parameter.
