A roaming device retains its home location device pool settings, even though all configuration settings are in place. What is causing this issue?

• A.The device mobility mode service parameter is set to True.

A company has a headquarters site and a remote site. Cisco Unified Communications Manager acts as a DHCP server. Both sites use their local voice gateways for PSTN calls. At the headquarters site, the PSTN prefix is 9, and the emergency number is 911. At the remote site, the PSTN prefix is 0, and the emergency number is 112. Here are the deployment policies for roaming devices:
* Softphones can roam between two sites.
* A roaming softphone uses the local gateway for all PSTN calls.
* The user keeps home dial habits on a roaming softphone, with the exception of the emergency number.
When a headquarters user uses a softphone at the remote site, the administrator notices that the PSTN calls are still going via voice gateway in the headquarters. The administrator enabled Device Mobility in the system parameters and on all phones. What are the next two components that the administrator must check, according to the flow of Device Mobility operation? (Choose two.)

• A.Device Mobility Info
• B.IP address of the softphone
• C.Physical Location
• D.Cisco Unified CM Group
• E.Device Mobility Group

Refer to the exhibit. In a multicluster environment using Call Control Discovery to advertise patterns between clusters, advertisements from one cluster are not propagating to other clusters. The output in the exhibit comes from the Cisco SAF Forwarder configured on this cluster. Why are advertisements failing?

• A.The SAF advertising service is not enabled
• B.The SAF security profile password is incorrect
• C.The SAF client label is incorrect
• D.The message integrity key is incorrect

Two Cisco DX80 collaboration endpoints that support high-definition video are registered to a Cisco Unified Communications Manager in a single-site deployment model. However, the video that is displayed is pixelated and appears as sub-HD. To enable the Cisco DX80s to make high-definition video calls, which configuration option do you check?

• A.Check the Maximum Session Bit Rate for Video Calls in the Cisco Unified Communications Manager Regions Configuration.
• B.Check the configuration in the Cisco DX80 settings menu, and enable high-definition video.
• C.Check the DSCP for Video Calls value in the Cisco Unified Communications Manager clusterwide parameters QoS configuration.
• D.Check that Video Capabilities are enabled under the Product Specific Configuration area for the device in Cisco Unified Communications Manager.
