Appendix H-Setting the Collaboration Server for Integration Into Microsoft Environment
Polycom, Inc. H-13
Setting the Numerical Dialing Method
The Collaboration Server can be configured as a Voice Gateway in the OCS environment,
enabling dialing in to meeting rooms using numbers instead of or in addition to SIP URI
addresses which are long strings.
In such configuration, HDX or MOC users dial a number rather than a full SIP URI,
simplifying the dialing, which is especially beneficial with the HDX remote control.
Such configuration also enables a common dialing plan for meeting rooms across OCS and
H.323 infrastructures. In an integrated environment that also includes Microsoft Exchange
Server and Polycom Conferencing Add-in for Microsoft Outlook, a single number can be
inserted into a calendar invitation and it will be valid for OC client endpoints and H.323
endpoints.
This dialing method can be configured in parallel to the matching URI dialing method
(using Static Routes).
Setting the Numerical Dialing for Collaboration Server Meeting Rooms
The following processes are required to set up the numerical dialing for the Collaboration
Server Meeting Rooms in the OCS infrastructure:
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” on page H-37.
1 Modify the Management Network Service to include the DNS server and set the
Transport Type to TLS.
2 Create the security certificate (using one of the two available methods)
3 Define a SIP Network Service in the Collaboration Server and install the TLS certificate.
4 Modify 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” on page 6-1 and "Entry Queues” on
page 7-1.
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”.
