Configuring the MCU as a Routable Gateway

The MCU must be set as a routable voice gateway in the Office Communications Server
infrastructure. This does not restrict the MCU to just voice operation, rather it means that
the MCU can be set as a destination for a voice route in the Office Communications Server
infrastructure.
The Office Communications Server infrastructure uses the WMI class
MSFT_SIPTrustedAddInServiceSetting to store information for each voice gateway
in the infrastructure. Typically, these gateways are Office Communications Server
Mediation Servers, but in this case, the MCU is set as a voice gateway by creating a new
instance of the class MSFT_SIPTrustedAddInServiceSetting.
Polycom recommends using the Office Communications Server 2007 R2 Resource Kit Tools
to accomplish this.
To set up the MCU/DMA as a Voice Gateway:
1Download and install the Office Communications Server 2007 R2 Resource Kit Tools
from the following URL:

2Open a command prompt and navigate to where you installed the resource kit. For
example, C:\Program Files\Microsoft Office Communications Server
2007 R2\ResKit\.
