Collaboration Edge is an umbrella term for an architecture. It allows Jabber clients (Win/Mac/iOS/Droid) to be proxied though a server (Expressway E) in the DMZ back to Expressway C and then CUCM. Collaboration Edge also includes the ability to proxy remote CUCM registered video endpoints (SX20, EX90, etc.).
Currently Collaboration Edge components are/will be:
- VCS X8.1 software (called VCSc, VCSe, Expressway C, or Expressway E depending on deployment model. It’s one actual piece of software.)
- Jabber 9.6/9.7 software (depending on platfrom)
- TC 7.0 video endpoint firmware
- CUCM 9.1
Expressway C and Expressway E is analogous of the VCS Control/VCS Express model, except that it is only for CUCM registered endpoints. It is actually VCS software. VCS Control is called “Expressway C” and VCS Expressway called “Expressway E” when deployed as Collaboration Edge (Jabber proxy, and endpoint proxy to CUCM) only. Depending on size, scale and deployment model it may run co-resident if you already have VCS deployed, or you may need to stand up two new VMs to run it.
VCS X8.1 is now out – the terminology it uses for the Collaboration Edge functionality is “Mobile and Remote Access” It is called a feature preview in 8.1, and will be prime-time in 8.1.1. – Release notes have some details here – http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/release_note/Cisco-VCS-Release-Note-X8-1.pdf
