Configure Device Pools

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 system, device, and location-related information.

After adding a new device pool, you can use it to configure devices such as Cisco Unified IP Phones, gateways, conference bridges, transcoders, media termination points, voice-mail ports, CTI route points, and so on.

Perform these steps:

1. Log in as provider, reseller, or customer administrator.

2. If you’re logged in as:

   • Provider or reseller administrator: Go to Apps Management > CUCM > Device Pools.
   • Customer administrator: Go to Apps Management > Advanced > CUCM > Device Pools.

3. Do you want to …

   • Add a new device pool? Click Add. On the dialog, choose the network device list (NDL) where you’re adding the device pool; then, click OK.

     Note

     The dialog to choose a NDL does not display if you’re adding the device pool instance to to site hierarchy node (you won’t need to choose a NDL). In this case, you will add the device pool using the NDL associated with the site.

   • Edit an existing device pool? Click the line item in the table. Go to step 4.

4. Click through the following tabs to complete at least the mandatory details:

   • Device Pool Settings tab
   • Local Route Group Settings tab
   • Roaming Sensitive Settings tab
   • Device Mobility Related Information tab
   • Geolocation Configuration** tab
   • Incoming Calling Party Settings tab
   • Incoming Called Party Settings tab
   • Caller ID for Calls from This Phone tab
   • Connected Party Settings tab
   • Redirecting Party Settings tab

5. Click Save. The route partition appears in the device pool list.

   To modify any of these properties, make your changes and click Save.

   To delete a device pool, select the check box adjacent to the Name column in the group list, and click Delete.

Device Pool Settings Tab

Option	Description
Device Pool Name *	Enter the name of the new device pool that you are creating. You can enter up to 50 characters, which include alphanumeric characters, periods (.), hyphens (-), underscores (_), and blank spaces. Default value: None
Cisco Unified CM Group *	Choose the Cisco Unified Communications Manager group to assign to devices in this device pool. A Unified CM group specifies a prioritized list of up to three Unified CMs. The first Unified CM in the list serves as the primary one for that group. The other members of the group serve as backup Unified CMs 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 Unified CM. The calling search space specifies partitions that devices can search when attempting to complete a call.
Adjunct CSS	From the drop-down list, choose an existing Calling Search Space (CSS) to use for the devices in this device profile as an adjunct CSS for the Extension Mobility Cross Cluster (EMCC) feature. To configure a new CSS or modify an existing CSS, choose Call Routing > Class of Control > Calling Search Space in Unified CM Administration. When configuring the EMCC feature, the administrator must configure a device pool for each remote cluster. If the remote cluster is located in a different country, the adjunct CSS must embrace the partition with which the emergency patterns of that country associate. This configuration facilitates country-specific emergency call routing. Default value: None
Reverted Call Focus Priority	Choose a clusterwide priority setting for reverted calls that the hold reversion feature invokes. 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 Unified CM. Note: This setting applies specifically to hold reverted calls; it does not apply to parked reverted calls.
Intercompany Media Services Enrolled Group	Choose an Intercompany Media Services Enrolled Group from the drop-down list.

Local Route Group Settings Tab

Option	Description
Local Route Group	From the drop-down, choose the name of the local route group to associate with this device pool.
Route Group	From the drop-down, choose the value for the local route group to associate with this device pool.

Roaming Sensitive Settings Tab

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. Default value: None
Region *	Choose the Unified CM region to assign to devices in this device pool. The Unified CM region settings specify voice codec that can be used for calls within a region and between other regions. Default value: None
Media Resource Group List	From the drop-down list, 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 defined in a media resource group list. Default value: None
Location	Use locations to implement call admission control (CAC) in a centralized call-processing system. CAC enables you to regulate audio quality and video availability. It works by limiting the amount of bandwidth that is available for audio and video calls over links between locations. The location specifies the total bandwidth that is available for calls to and from this location. From the drop-down list, choose the appropriate location for this device pool. A location setting of None or Hub_None means that the locations feature does not track the bandwidth that the devices in this pool consume. A location setting of Phantom specifies a location that enables successful CAC across intercluster trunks that use H.323 protocol or SIP. Default value: None
Network Locale	From the drop-down list, 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 can support. Note: If the user does not choose a network locale, the locale that is specified in the Unified CM 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. When a device is associated with a network locale that it does not support in the firmware, the device fails to come up. Default value: None
