Which service handles instant messaging and presence in Cisco collaboration?

• A. Webex Calling
• B. Unity
• C. Expressway
• D. Cisco Unified IM and Presence

Answer: (D)

Instant messaging and presence are provided by the Cisco Unified IM and Presence service. This component is responsible for real-time text messaging and showing users’ presence status (online, away, busy) to clients like Cisco Jabber. It stores messages, routes them to the right user, and integrates with the call-control backbone to unify messaging with calling. The other options don’t host this service: Webex Calling focuses on voice calling; Cisco Unity handles voicemail and related messaging; Expressway covers edge traversal and secure access for IM&P traffic but does not itself deliver the IM and presence service. So the correct choice for instant messaging and presence is Cisco Unified IM and Presence.
