Appendix H - Integration Into Microsoft Environments
Polycom®, Inc. 720

OCS side:

●Configuring the Collaboration Server as a Routable Gateway - The Collaboration Server (or DMA)
must be set as a trusted voice gateway in the OCS infrastructure. This does not restrict Collaboration
Server to just voice operation, rather it means that the Collaboration Server (or DMA) can be set as
a destination for a voice route using the OCS management console.
Setting the Collaboration Server as a trusted voice gateway also enables it to be used as a trusted
gateway for static routes using URI matching.
●Establishing a Voice Route to the Collaboration Server “Voice” Gateway - The Voice Route to the
Collaboration Server (or DMA) must be configured in the OCS infrastructure.
●Configure Office Communicator Users for Enterprise Voice.

Collaboration Server side:

The following tasks are detailed in Configuring the Collaboration Server for Microsoft Integration.
1Modify the Management Network Service to include the DNS server and set the Transport Type to
TLS.
2Create the security certificate (using one of the two available methods)
3Define a SIP Network Service in the Collaboration Server and install the TLS certificate.
4Modify and add the required system flags in the Collaboration Server System Configuration.
5 Optional. Defining additional Entry Queues and Meeting Rooms in the Collaboration Server
environment. For details see Meeting Rooms and Entry Queues.
For a detailed description of the configuration of the Polycom conferencing components for the integration
in Microsoft Office Communications Server 2007 see the Polycom® HDX and Collaboration Server™
Systems Integration with Microsoft Office Communications Server 2007 Deployment Guide.
Optional. Removing the Collaboration Server from the Host Authorization List
If you have defined the Collaboration Server as Trusted Host to enable dialing using the Static Routes and
you want to use numerical dialing in addition or instead of SIP URI dialing, you need to remove the current
definition of the Collaboration Server and redefine it as a voice gateway.

To remove the definition of the Collaboration Server as trusted host from the Front End

Properties:

1In the OCS application, display the Front End Properties (right-click the Front End and select
Properties).
2Click the Host Authorization tab.
3In the Trusted Hosts list, click the Collaboration Server entry and then click the Remove button.
If the Collaboration Server was previously defined as a Trusted Host for matching URI dialing
method, this definition must be removed before configuring the Collaboration Server as a voice
gateway. It will be defined as trusted host as part of the voice gateway configuration. For more
details, see Optional. Removing the Collaboration Server from the Host Authorization List.
