However, you must assign users and enable the IM and Presence Service for each assigned user. With the Jabber for Everyone offer, no end user licenses are required to enable IM and Presence Service functionality. For more information, see Jabber for Everyone Quick Start Guide. Note You can assign IM and Presence Service on a per user basis, regardless of the number of clients you associate with each user. When you assign IM and Presence Service to a user, this enables the user to send and receive IMs and availability updates. If users are not enabled for IM and Presence Service, they will not be able to log in to the IM and Presence Service server to view the availability of other users, send or receive IMs, and other users will not see their availability status. You can enable a user for IM and Presence Service using any of the following options: • The End User Configuration window in Unified Communications Manager. For more information, see the Administration Guide for Cisco Unified Communications Manager. • The Bulk Administration Tool (BAT) • Assign IM and Presence Service to a feature group template which you can reference from the Quick User/Phone Add window in Unified Communications Manager.
