Using a hardware-based phone device such as Polycom or Microsoft’s own Tanjay with built-in Office Communicator 2007 client, you may be prevented from signing in even after you supplied valid credentials. The typical error message looks like this:

Your account is not configured to use this service. Please contact your system administrator.

To fix this, fire up the OCS 2007 mmc and drill down all the way to the Users container. Highlight, right mouse click on the OC-enabled user and choose Properties. On the Communications Tab, click on Configure and select the “Enable Enterprise Voice” radio button (default = “Enable PC-to-PC communications only”). In the Line URI field, enter a valid E.164 number in the form “tel:+41441234567″.

Do not forget that in order to enable this and other enterprise features (supported on Standard and Enterprise editions), the appropriate type and number of client access licenses must be separately procured.
