Instant messaging features

Using the collaboration clients on their BlackBerry devices, users can use many of the same features that are available in the instant messaging applications on their computers.

Feature	Description
session management	You can specify the number of simultaneous instant messaging sessions that
	the BlackBerry Collaboration Service supports. You can also specify a timeout
	threshold, after which the BlackBerry Collaboration Service ends inactive
	sessions automatically and permits new sessions to start.
	You can control whether users of specific versions of the BlackBerry Client for
	IBM Sametime or the BlackBerry Client for Novell GroupWise Messenger can
	see an icon on their BlackBerry devices when contacts in their contact lists are
	using the same collaboration clients. By default, the icon appears.
conversations with multiple contacts	Users can start and manage conversations with multiple instant messaging
	contacts on their BlackBerry devices.
availability status	Users can change their availability status when they are logged in to their
	collaboration clients. For example, users can set their availability status to away
	or busy.
presence updates	Using the latest versions of the collaboration clients, users can set their
	availability status to display as away if they do not use their BlackBerry devices
	for a specified period of time.
access levels	Using the latest version of the BlackBerry Client for use with Microsoft Office
	Communications Server 2007, users can set the access level of contacts in their
	contact lists. Each access level consists of rules that define how contacts can
	interact with a user through the instant messaging application. For example,
	users can assign the Personal access level to their contacts.
contact pictures	Using the latest versions of the collaboration clients, users can add pictures to
	the contacts in their contact lists. The pictures that users add using the
	collaboration clients on their BlackBerry devices are not synchronized with the
	instant messaging applications on users' computers.
