Per Cisco: Important use cases for Cisco VCS include:
- Business-to-business video: Using Uniform Resource Identifier (URI) dialing, you can collaborate with customers, partners, and suppliers as easily and securely as you do with email messages. No prearrangements are needed. And, if your partners, suppliers, or customers have a third-party standards-based H.323, H.264 switched virtual circuit (SVC), or Session Initiation Protocol (SIP) system, you can collaborate with them too – as easily as you do with those people in your own office.
- Mobile video experiences using Cisco Jabber® for TelePresence (formally Movi™) clients: Secure mobile access based on Transport Layer Security (TLS), Cisco Jabber® for TelePresence mobile lets you make and receive video calls without requiring the extra step of a VPN.
- Teleworkers: Teleworkers can use their personal Cisco TelePresence endpoints for video interactions with colleagues, customers, partners, and suppliers from their home office.
- Investment protection: The solution offers video interoperability with your current standards-based H.323, H.264 SVC, and AVC or SIP systems and devices.
When Cisco VCS is deployed with Cisco Unified Communications Manager or Cisco Business Edition 9.1.2 or later, the following is also possible when remote and mobile access to Cisco Unified Communications Manager is enabled:
- Mobile experiences using any Cisco Jabber client with access to all collaboration workloads (video, voice, content, instant messaging, and presence) without requiring the extra step of a VPN.
- VPN-less teleworker support for Cisco TelePresence personal endpoints (Cisco TelePresence EX, MX, SX and C Series as well as Cisco Jabber).
- Mobile and browser-based collaboration with Jabber Guest: Realize the benefits of new ways of securely and easily interacting with “guests” whether they are consumers, other businesses, or even temporary employees.
