if the PUA is configured so that registered devices do not report ‘Available’, presence will always

VCS supports a maximum of 100 presence subscriptions per presentity
Small test/demo networks
For small test and demo networks, video endpoints may be registered to the “OCS/Lync gateway”
VCS Control, the small video network being controlled by the same Cisco VCS that is the interface to
OCS/Lync server.

Scaling up from a small test/demo network
As extra capacity, regional management and reduced license usage is required it is possible to scale
away from the ‘small test and demo network’ system to the “OCS/Lync gateway” VCS connected to
video network approach. This is achieved by adding video network VCSs and neighboring them
(directly, or indirectly through other VCSs) to the “OCS/Lync gateway” VCS. Endpoints can be added
to the video network VCSs and endpoints and other devices then gradually migrated off the
“OCS/Lync gateway” VCS onto the video network VCSs.

Cisco VCS can interoperate with both OCS 2007 R2 Standard and Enterprise edition.
Version X6.1 or later is required to support Lync Standard edition and Lync Enterprise edition.
Version X7.0 or later is required to support VCS B2BUA
Beyond X7.x it is expected that OCS Relay will no longer be available

Domain static route(s) can be set up on OCS/Lync Server to route calls to, for example an MCU
domain – useful for ad-hoc conferences. (Care must be taken when using domain static routes; a
static route means that OCS/Lync will send all traffic for that domain that it cannot handle to VCS).
