Using SIP-SIMPLE, OCS/Lync Server only supports the reception of the “available” status, so
presence is limited to buddies indicating “gray” (not available), or “green” (available). “In-call” and
other rich presence states are not handled.
Also VCS only supports a maximum of 100 subscriptions per presentity.

using SIP-SIMPLE and so no presence information can be supplied to endpoints registered on
Cisco VCS about endpoints registered on OCS/Lync server.

Cisco VCS configuration
If endpoints registered to the Cisco VCS Control supply their own presence information the Cisco VCS
Control only needs to be a Presence Server, aggregating presence information and providing
presence status to users who subscribe for the information.

If endpoints registered to the Cisco VCS Control do not support the generation of presence

To configure presence on the Cisco VCS Control:
1. Go to the
Presence
page (
Applications > Presence
).
2. Configure the following fields:
