What is the main difference between Cisco Jabber and Cisco Jabber Video for TelePresence?

Cisco Jabber is a unified communications client that registers to Cisco Unified Communications Manager (CUCM) for call control, integrating voice, video, messaging, and presence through the CUCM infrastructure. Cisco Jabber Video for TelePresence (formerly known as Movi) registers to the Cisco TelePresence Video Communication Server (VCS), which is designed for standards-based H.323 and SIP video conferencing environments. This difference in registration target reflects the two distinct collaboration deployment architectures the products are designed to serve.

This reverses the registration targets - Jabber Video for TelePresence registers to VCS, not CUCM, and Cisco Jabber registers to CUCM, not VCS.

Cisco Jabber supports video calling; it is a full unified communications client with audio, video, messaging, and presence capabilities.

Presence awareness is a core built-in capability of Cisco Jabber, not a missing feature.

There is a clear and significant architectural difference between the two products based on their respective call control registration targets.
