Which portal is used to manage end-user settings and features in Webex Calling?

The correct answer, which identifies the portal used to manage end-user settings and features in Webex Calling, is the Calling User Portal. This portal is specifically designed for end users to manage their personal settings, such as call forwarding, voicemail, and user preferences. It provides a user-friendly interface where individual users can make changes to their call handling features and access other personalized functionalities related to their Webex Calling service.

In contrast, while the User Management Portal provides administrators with tools to manage users and their permissions, it does not focus on end-user settings. The Settings Dashboard generally offers broader configurations and settings, often aimed at organizational settings rather than individual user management. The Control Center primarily serves as a centralized management interface for deploying, monitoring, and maintaining services across the Webex environment rather than focusing on specific end-user features. Therefore, the Calling User Portal is the most relevant and appropriate choice for managing individual user settings in Webex Calling.
