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

Matched URI Method

Once the MCU is configured for integration in the OCS environment (for details, see
"Configuring the RMX 1500/2000/4000 for Microsoft Integration” on page H-36), 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 MCU 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 MCU Meeting Rooms

The following processes are required to set up the numerical dialing for the MCU Meeting
Rooms in the OCS infrastructure:
OCS side:
• Configuring the MCU as a Routable Gateway - The MCU (or DMA) must be set as a
trusted voice gateway in the OCS infrastructure. This does not restrict MCU to just
voice operation, rather it means that the MCU (or DMA) can be set as a destination for a
voice route using the OCS management console.
Setting the MCU as a trusted voice gateway also enables it to be used as a trusted
gateway for static routes using URI matching.
