A customer wants to deploy Cisco Jabber Phone Mode with contacts. Which two configurations are needed to accomplish this goal? (Choose two)

The "Application Client Users role" is generally for applications (like CTI applications) to access UCM, not a standard requirement for individual end-users to use Jabber Phone Mode with contacts.

Removing IM and Presence servers from the UCM service profile would prevent Jabber from discovering and connecting to the IM and Presence server altogether, thereby disabling contact list functionality, which contradicts the requirement "with contacts."

To achieve "Phone Mode" where the primary focus is calling and contacts without full Instant Messaging capabilities, the Instant Messaging service must be explicitly disabled on the Cisco IM and Presence server. This prevents users from initiating or receiving IMs while still allowing them to access their contact list.

Importing a Contacts.xml file is not a standard or scalable method for populating user contact lists in an enterprise Jabber deployment; contacts are typically managed through IM&Presence server integration with directories.

Even if Instant Messaging is disabled, the Cisco Jabber client requires connectivity to the IM and Presence server for contact list management. Therefore, the Cisco UCM end-users must be enabled and provisioned for IM and Presence Services to allow them to fetch, store, and manage their contact lists.
