The OCS Relay application is required in deployments that use
both Microsoft Office Communicator (MOC) clients and FindMe,
where they both use the same domain. It enables the VCS to:

•

share FindMe presence information with MOC clients

•

register FindMe users to a Microsoft Office Communications
Server (OCS) so that the OCS can forward 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.

Configuring OCS Relay

Viewing OCS Relay status

VCS Configuration

The OCS Relay page (Applications > OCS Relay) allows you to
enable and disable the OCS Relay application on the VCS, and
configure the settings it uses. The options are:

OCS Relay mode
This field allows you to enable (On) and disable (Off) the OCS
Relay application on the VCS.

OCS Relay domain
The OCS Relay is used in deployments where MOC clients and
FindMe aliases use the same domain. The domain to be used
must already be configured on the VCS (VCS configuration >
Protocols > SIP > Domains). You can then select the domain
from the drop-down menu.

OCS Relay routing prefix
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. In order 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 will ensure that all requests with the specified prefix are
routed directly to the OCS.

Other requirements

There are a number of other steps required in order to
successfully set up a connection between the VCS and OCS.
These include:

•

creating an appropriate neighbor zone

•

configuring Call Policy

•

configuring Presence

As this is a complex procedure beyond the scope of this
Administrator Guide, you are recommended to refer to the

Microsoft OCS 2007 (R1 and R2) and VCS Control Deployment
Guide [24]

which describes in detail all the steps required.

The OCS Relay status page (Status > Applications > OCS
Relay) lists all the FindMe aliases being handled by the OCS
Relay application, and shows the current status of each, as
follows:
Registration state
This indicates whether the FindMe alias has registered
successfully with OCS. This allows OCS to forward calls to the
FindMe alias.
Subscription state
This indicates whether the OCS Relay application has subscribed
successfully to the FindMe alias's presence information. This
will allow MOC clients to view the presence information of
FindMe users.
Presence State
This shows the presence information currently available for the
FindMe alias.
