Cisco WebEx Connect was a cloud-based team messaging platform, not a full unified communications client designed for mobile corporate network access with voice and video.

Cisco Unified Presence is a server-side service that aggregates and publishes presence information, not an end-user client application for mobile collaboration.

Cisco TelePresence SX20 is a fixed room-based video codec for conference rooms, not a mobile user client for personal communication.

Cisco Jabber is a software-based unified communications client that runs on mobile and desktop platforms, integrating with Cisco Unified Communications Manager to deliver voice calls, video conferencing, instant messaging, presence, and web collaboration in a single application. It is specifically designed to extend corporate communication capabilities to mobile workers over any network connection.
