Device Pools

Overview

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, and CTI route points.

Add or Manage Device Pools

1. Log in to the Admin Portal as Provider, Reseller, or Customer administrator.

2. If you’re logged in as:

   • Provider or Reseller administrator: Go to (default menus) Apps Management > CUCM > Device Pools.

   • Customer administrator: Go to (default menus) Apps Management > Advanced > CUCM > Device Pools.

3. Choose an option:

   To add a new device pool	Click Add. Choose the network device list (NDL) where you want to add the new device pool. Note You won’t need to choose a NDL if you’re adding the device pool at a site. In this case, you will use the NDL associated with the site. Click OK. On the Device Pool Settings tab, at Device Pool Name, fill out the device pool name as RSMSimPhone_DP. From the Cisco Unified CM Group drop-down, choose RSMSimPhone. On the Roaming Sensitive Settings tab, from the Date/Time Group drop-down, choose the appropriate date/time group. From the Region drop-down, choose AR_ RSMSimPhone. From the SRST Reference drop-down, choose Disable.
   To edit a device pool	Click on the relevant device pool in the list. Go to step 4.
   To delete a device pool	In the list view, select the checkbox adjacent to the Name column for the device pool you want to remove. Click Delete.

4. To configure or update device pool properties, click through the tabs on the page and fill out at least the mandatory fields:

   • 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.

Associate a Local Route Group to a Device Pool

This procedure associates a local route group with an existing device pool for each site.

This allows calls from a device that is tied to a device pool to go out on a specific route group based on the call type. For example, you can associate multiple local route groups such as Emergency Route Group, Primary Local Route Group (for site A), Secondary Local Route Group (for site A), Primary Local Route Group (for site B), and Secondary Local Route Group (for site B).

Local Route groups allow you to specify different route groups for each site (site A and site B) for the respective device pool. Also, you can define a separate call routing option for emergency calls when you associate the Emergency Route Group with a different route group. Hence you can easily define separate call routing options for emergency calls and PSTN calls.

1. Log in as Provider, Reseller, or Customer administrator.

   Warning

   When associating a local route group, ensure that you select a valid site under your customer in the hierarchy node breadcrumb at the top of the view. If you attempt to associate a local route group at any other node in the hierarchy, a popup alerts you to select a site hierarchy node.

2. Choose an option:

   • Logged in as Provider or Reseller admin? Go to (default menus) Apps Management > CUCM > Device Pools.

   • Logged in as Customer admin? Go to (default menus) Apps Management > Advanced > Device Pools.

3. Click the device pool to be associated.

4. From the Cisco Unified CM Group drop-down menu, select a specific Cisco Unified Communications Manager group or leave the Cisco Unified CM Group as Default.

5. Configure setting in the Local Route Group Settings tab/panel:

   1. In the grid, from the Local Route Group drop-down menu, select the local route group.

   2. In the grid, from the Route Group drop-down menu, select the route group or gateway.

6. Save the new local route association.

Device Pools Configuration Settings

Device Pool Settings

The table describes the device pool settings and values on the Device Pool Settings tab/panel:

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

The table describes the device pool settings and values on the Local Route Group Settings tab/panel:

Roaming Sensitive Settings

The table describes the device pool settings and values on the Roaming Sensitive Settings tab/panel:

Option	Description
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

Option	Description
