Configuring the Collaboration Server System

The required tasks are detailed in Configuring the Collaboration Server for Microsoft Integration.

Dialing to an Entry Queue, Meeting Room or Conference Using the Matched URI

Method

Once the Collaboration Server is configured for integration in the OCS environment, the preferred dialing
mode to the conferencing entities such as Meeting Rooms, conferences and Entry Queues is direct dial in
using the domain name defined in the OCS Static Routes. This eliminates the need to register the
conferencing entities with the SIP server and to define a separate user for each conferencing entity in the
Active Directory.
In such a case, after the first dial in, the conferencing entity will appear in the OC client directory for future
use.

To dial in directly to a conference or Entry Queue:

Enter the conferencing entity SIP URI in the format:
conferencing entity routing name@domain name
The domain name is identical to the domain name defined in the OCS Static Routes.
For example, if the domain name defined in the OCS static routes is lcs2007.polycom.com and the Routing
Name of the Meeting Room is 4567, the participant enters 4567@lcs2007.polycom.com.
Another dialing method is to register the Entry Queues with the SIP Server and create a user for each Entry
Queue in the Active Directory. In such a case, OC clients can select the Entry Queue from the Contacts list
and dial to the Entry Queue.
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:
Make sure that when defining the Static Route it is pointing to the OCS pool and not to the
Collaboration Server directly.
