Blocking Calls to Certain Destination Numbers
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
There are situations where the administrator would like to block calls from the enterprise to certain destinations due to toll-charges (for example, premium numbers like 1900 numbers, operator assistance, and 1411).
Note that the current release of Office Communications Server does not allow for a configuration that can be used to explicitly block a destination, calls are blocked implicitly if there is no matching pattern found in the Routing table.
For example, if the administrator chooses to block calls to 1900 and 1411 numbers, they would have to define regular expressions that exclude 1900*. The following configuration shows an example of how this may be accomplished, and does not preclude other ways of accomplishing the same effect.
