Appendix H-Setting the Collaboration Server for Integration Into Microsoft Environment
Polycom, Inc. H-7
For a detailed description of the configuration of the Polycom conferencing components for 
the integration in Microsoft Office Communications Server 2007 see Polycom® HDX and 
Collaboration Server™ Systems Integration with Microsoft Office Communications Server 2007 
Deployment Guide.
In ICE environment, to enable the Matched URI dialing in the federated environment to be 
able to connect to the Collaboration Server SIP signaling domain, you must also configure 
the Office Communications Server. When federating an Office Communications Server edge 
server with another Office Communications Server environment, you need to include the 
FQDN of the Office Communications Server edge server as well as the SIP signaling domain 
for federated environment. The SIP signaling domain is the FQDN of the Polycom DMA 
system or a Polycom Collaboration Server system (when your deployment does not include 
a DMA system).
Note: The RMX does not support working with multiple edge servers.
For example, if company B wants to set up federation with company A and receive and send 
SIP calls that will be handled by the Polycom SIP signaling domain in company A, you need 
to add the FQDN of the company A Office Communications Server domain as well as the 
SIP signaling domain of company A to the list of Internal SIP Server domains supported by 
the company B Office Communications Server environment.
For more information, see the Microsoft documentation and the Visual Communications 
Deployment Administration Guide.
Configuring the Office Communications Server for Collaboration 
Server Systems
To be able to work with the Office Communications Server, the Collaboration Server unit 
must be configured as a Trusted Host in the OCS. This is done by defining the IP address of 
the signaling host of each Collaboration Server unit as Trusted Host.
Meeting Rooms are usually not registered to the OCS, and Static Routes are used instead. 
Setting Static Routes in the OCS enables SIP entities / UAs to connect to conferences 
without explicit registration of conferences with the OCS. 
Routing is performed by the OCS based on the comparison between the received URI and 
the provisioned static route pattern. If a match is found, the request is forwarded to the next 
hop according to the defined hop’s address. 
This is the recommended working method. It alleviates the need to create a user account in 
the OCS for each Meeting Room and Entry Queue. This also allows users to join ongoing 
conferences hosted on the MCU without registering all these conferences with OCS. 
Entry Queues can also be for Ad-hoc conferencing enabling Office Communicator clients to 
dial to the Entry Queue and create a new ongoing conference using DTMF codes to enter the 
target conference ID. In such a case, other OC users will have to use that ID to join the newly 
created conference. 
Setting the Trusted Host for Collaboration Server in the Office 
Communications Server
To set the Collaboration Server as trusted in OCS:
1 Open the OCS Management application.
