Which two Device Pool configuration settings will override the device-level settings when a device is roaming within or outside a device mobility group? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
The parameters under these settings will override the device-level settings when the device is roaming within or outside a Device Mobility Group.
The parameters included in these settings are: Date/time Group.
Media Resource Group List.
Device Mobility Group.
The roaming sensitive settings primarily help in achieving proper call admission control and voice codec selection because the location and region configurations are used based on the device's roaming device pool.
The correct answers are B. Device Mobility CSS and C. Network Locale.
Device pools are used to group devices with similar characteristics, such as IP phone models, device types, or geographic locations. They allow you to configure settings that apply to all devices in the pool, such as the region, codec, date/time, and so on.
Device Mobility is a feature that allows IP phones or other devices to maintain their settings and services when they roam between different locations, such as branches, campuses, or cities. Device Mobility groups are created to define the boundaries of the roaming area, and to specify the local and remote settings for devices that belong to the group.
When a device roams within or outside a Device Mobility Group, the following device-level settings can be overridden by the device pool or Device Mobility Group configurations:
B. Device Mobility CSS: This setting determines the Calling Search Space (CSS) that a device uses to access route patterns, translations, and other call-routing objects when it roams to a different location. If a device pool or Device Mobility Group has a different CSS configured, it will take precedence over the device-level CSS.
C. Network Locale: This setting defines the country-specific settings for a device, such as the dial plan, date/time format, and audio prompts. If a device pool or Device Mobility Group has a different network locale configured, it will override the device-level locale.
The other settings listed in the answer choices do not directly affect the roaming behavior of devices, or they are not related to device pools or Device Mobility groups.
A. Adjunct CSS: This setting defines the CSS that a CTI route point uses to access partitions and translation patterns. It is not related to device pools or Device Mobility groups.
D. Called Party Transformation CSS: This setting determines the CSS that is used to transform the called party number in a call. It is not related to device pools or Device Mobility groups.
E. AAR CSS: This setting specifies the CSS that is used for Automated Alternate Routing (AAR), which is a feature that routes calls over an alternate path when the primary path is congested. It is not related to device pools or Device Mobility groups.
F. Device Mobility Group: This is the group that defines the boundaries of the roaming area, and the local and remote settings for devices that belong to the group. It is not a device pool configuration setting, but a feature that relies on device pools.
