      operationId: Read the Contact Center Extensions
      description: "Retrieves the Contact Center phone number, extension, virtual numbers, endpoints, and endpoints registration status associated with the authenticated user. This API returns all primary and secondary endpoints, the hot desk guest profiles currently hosted on the agent's own devices, if any, and registration status of those endpoints. Only virtual line extensions hosted exclusively on the agent's devices and the registration status of those virtual line endpoints will be retrieved. Any virtual lines shared with devices not owned by the current user will be excluded.\n\n A Webex Calling Contact Center extension is a calling extension assigned to a user or device within the Webex Contact Center for internal dialing.\n\nThis API requires a user auth token with a scope of spark:telephony_config_read."
