Ocs Relay - Cisco TelePresence Administrator's Manual

OCS Relay

Note: from VCS software version X7 you are recommended to use the
SIP calls between the VCS and a Microsoft OCS/Lync Server.
The OCS Relay page (Applications > OCS
application on the VCS, and configure the settings it uses. The OCS Relay application is required in
deployments that use both MOC clients and FindMe, where they both use the same SIP domain. It enables
the VCS to:
share FindMe presence information with MOC clients
n
register FindMe users to a Microsoft Office Communications Server (OCS) so that the OCS can forward
n
calls to FindMe aliases
Deployments where the MOC clients and FindMe do not use the same domain do not require use of the OCS
Relay application.

same domain. The domain to be used must already be configured on the VCS

OCS Relay routing Prefix applied to the SIP domain of requests destined for OCS. This prefix is used by the
prefix VCS search rules to route the requests via the appropriate neighbor zone to the Microsoft
Office Communications Server. The default is ocs.

Configuring a connection between the VCS and the OCS
To create a connection between the VCS and the OCS, you must have already configured a neighbor zone
on the VCS with details of the OCS. For the OCS Relay application to be able to route requests to this OCS,
you must then:
1. Configure the VCS with an OCS Relay routing prefix.
2. Configure a search rule for the OCS neighbor zone that has a pattern match for that OCS Relay routing
prefix.
This ensures that all requests with the specified prefix are routed directly to the OCS.
There are a number of other steps required in order to successfully set up a connection between the VCS and
OCS, including configuring Call Policy and Presence. As this is a complex procedure beyond the scope of
this guide, you are recommended to see
