Problem description

You cannot prevent Office Communicator 2007 from controlling the call forwarding settings. In some scenarios, Office Communicator 2007 will overwrite the Private Branch Exchange (PBX) forwarding settings. This causes you to lose some important calls.


To resolve this problem, you must first install the update that is described in Microsoft Knowledge Base article 957465. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
957465  ( ) Description of the Communicator 2007 hotfix rollup package: December 19, 2008
Then you must enable the new policy that this update provides. This policy disables the call forwarding settings from Office Communicator for a Remote Call Control user. After this policy is applied, Office Communicator no longer controls forwarding settings on the PBX.

To have us enable this policy for you, go to the “Fix it for me” section after you have installed the update. If you would rather enable this policy yourself, go to the “Let me fix it myself” section after you have installed the update.

Fix it for me

To enable the policy automatically, click the Fix this problem link. Then click Run in the File Download dialog box, and follow the steps in this wizard.
