RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator’s Guide
Polycom®, Inc. 1015
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 Collaboration Server 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 Collaboration Server/DMA as a Voice Gateway:
1 Download and install the Office Communications Server 2007 R2 Resource Kit Tools from the
following URL:

2 Open a command prompt and navigate to where you installed the resource kit. For example,
C:\Program Files\Microsoft Office Communications Server 2007 R2\ResKit\.
3 Run the following command:
cscript OCSTrustEntry.vbs /action:add /type:trustedservice /fqdn:<your
FQDN> /service:MediationServer /port:5061 /version:4 /routable:TRUE
Where <your FQDN> is the FQDN of your Collaboration Server system. The script automatically
generates the GUID discover the proper Active Directory container to store the object.
Your Collaboration Server system is now established as a trusted gateway by all Office
Communications Server pools in the domain. It is displayed in the list of voice gateways when you
establish a voice route.
Establishing a Voice Route to the Collaboration Server “Voice” Gateway
The OCS infrastructure enables you to establish a voice route to a voice gateway. Typically, this means that
all SIP INVITEs to phone numbers which match a particular pattern will be routed to a specific gateway. In
this example, all INVITEs to numbers which start with “11” will be routed to Collaboration Server11 (DNS
name rmx11.r13.vsg.local2).
