The correct answer is C.The Extension Mobility feature can be described as follows1:
The Cisco Unified CM feature that allows Agents to temporarily access their Cisco Unified IP Phone configuration, such as line appearances, services, and speed dials, from other Unified IP Phones1.
The feature enables users to log in to any phone that supports Extension Mobility and use it as their own phone1.
The feature supports both intra-cluster and cross-cluster scenarios, where users can log in to phones that are located within the same or different Unified CM clusters1.
The other options are incorrect because:
Option A is incorrect because the device profile needs to be created in Unified CM, not CCE, and associated with the user, not the agent1.
Option B is incorrect because only the device profile needs to be added to the pg user account, not the phone2.
Option D is incorrect because the Extension Mobility Cross Cluster works on phones that are located in different Unified CM clusters, not the same cluster1.
Extension Mobility is a feature of Cisco Unified Communications Manager (CM) that allows users to temporarily access their personal phone settings, such as line appearances, services, and speed dials, on different Cisco Unified IP Phones. This feature is particularly useful in environments where users change workspaces frequently or share workspaces with others.References:Cisco Unified CM's official documentation provides comprehensive details on the Extension Mobility feature, including its setup, configuration, and usage.
