Multisite is a local endpoint feature which is unlocked with the MS (MultiSite) option key. The PR key is for PremiumResolution in order to do 1080p / 60 fps calls. The C60 can do 4 way multisite including yourself so you can host a multisite conference on the new C60 with the other 3 C60´s if you have the multisite option on this unit.
Do I have to use a BE-6K in the new site too for that?
The MultiSite is hosted on the local endpoint so it should work.
which are the licenses required?
What is the bandwidth requirement?
10 Mbps total multisite bandwidth is avalable 10/4=2.5 Mbps max per participant @ full MS utilization.
I heard that BE-6K have in-built VCS. What is the use of it? This questions should be more specific as the VCS has a lot of functionality. Please see the document link below, it´s on nearly 500 pages which is too much to cover here :) But short: It is a SIP/H323 registrar with flexible media and session management but it is a lot more than that. I do not know where to start, so I think it is best you read the document.
If you need it? You can alternatively register the C60´s to the CUCM. So you do not need the VCS for this particular purpose.
As I said the VCS has a lot of functionality you can read more about the VCS here: http://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/vcs/admin_guide/Cisco_VCS_Administrator_Guide_X7-2.pdf
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
