The Exchange UM Integration Utility (that is, Ocsumutil.exe) is a command-line tool that you can use to integrate Office Communications Server and Exchange Unified Messaging to enable Enterprise Voice messaging.
The tool has two functions:
- Create contact objects for all defined Exchange Unified
Messaging subscriber access and auto-attendants. These objects are
needed to route incoming subscriber access and auto-attendant calls
to Exchange Unified Messaging.
- Verify that the Exchange Unified Messaging SIP dial plan names
match the corresponding Office Communications Server location
profiles. This functionality is needed to enable the routing of
outgoing calls from Exchange Unified Messaging to Office
Communications Server and to ensure that the correct number
normalization is performed. The tool does not correct any
mismatches; it only displays them.
You can use the tool in the following situations:
- When initially configuring integration between Office
Communications Server and Exchange Unified Messaging. Unified
Messaging configuration needs to be completed before you run this
- When new Exchange Unified Messaging dial plans are installed
for Office Communications Server or when additional subscriber
access and auto-attendants are added to an existing Office
Communications Server-related dial plan.
- Troubleshooting inbound routing from Office Communications
Server to Exchange Unified Messaging subscriber access and
- Troubleshooting outbound routing from Exchange Unified
Messaging to Office Communications Server for features like Play on
Phone and Call Back.
OCSUMUtil.exe is available in the %InstallDir%\Microsoft Office Communications Server 2007 R2\Server\Support\ directory on a computer on which Office Communications Server 2007 R2 is installed. For details about running the Exchange UM Integration Utility, see in the Deploying Enterprise Voice documentation.
