i have a centeralised VCS-Cluster and a traversal zone created to local VCS-Expressway from this Cluster. I am planning to put 9 new VCS-Expressway in other 9 remote locations. So i would like to know is it possile to create a traversal zone from all these remote VCS-Expressway to this Centeralised VCSC Cluster???
If you have any document related to this please share it.

I do not know much about your deployment, but often a local VCS-C is used with e loal VCS-E to keep traffic, yes, local.
In your deployment all media will be bound to the VCS-C cluster and if I see it right all VCS-C would make a traversal
client connection to the traversal servers on the VCS-Es.
This might affect the way your traffic flows. If you want to have multiple internet pops and then make sure to
use your internal MPLS towards a centralized location it can be fine.
But if you have the VCS-C cluster in Europe for example, an internal user in Brazil and the VCS-E in Brazil as well
the traffic would flow Internet (Brazil)
-> VCS-E (Brazil) -> transport net to VCS-C (can be internal mpls, internet, ...) Europe -> Endpint (Brazil)
So: Brazil -> Europe -> Brazil
If you expect something like Brazil>Brazil you would need a VCS-C in brazil as well
Just look at the admin guide regards traversal zones and the cluster guide regarding clustering in general.
VCS documentation can be found here.

Hi Martin,
I am planning to register all Video Endpoints from Brazil there in Brazil VCSE itself and have a Traversal Zone created from Brazil VCSE to Europe VCSC-Cluster. The same way i am planing to do the design for all other remote branches as well.
In this scenario the Europe VCS-Cluster will act as core for all other VCSE in remote branches.
I have an existing VCSE is already connected to Europe VCSC-Cluster.
My main concern is how many Traversal Server(VCSE which placed in Remote branches) can get connect to one Traversal Client(VCSC Cluster in Europe)??? is this possible or i need to have VCSC in all other remote locations as well.

9 shall be a peace of cake = no problem.
The admin guide does not define something special besides up to 1000 zones can be defined:
(snip from the x7 admin guide):
You can configure up to 1000 zones. Each zone is configured as one of the following zone types:
* Neighbor aconnectiontoaneighborsystemofthelocalVCS.
* Traversalclient thelocalVCSisatraversalclientofthesystembeingconnectedto,andthereisafirewall
between the two.
* Traversalserver thelocalVCSisatraversalserverforthesystembeingconnectedto,andthereisa
firewall between the two.
* ENUM thezonecontainsendpointsdiscoverablebyENUMlookup.* DNS thezonecontainsendpointsdiscoverablebyDNSlookup.
But theory and praxis is not the same.
This deployment sounds a bit special and I would contact your Cisco partner to make you aware
of the possible media flow and license usage implications and think of further options/deployment modes.
