Configure Routing of Unassigned Phone Numbers


Topic Last Modified: 2010-12-13

In Microsoft Lync Server 2010, you can specify what happens to incoming calls to phone numbers that are valid for your organization but are not assigned to a user or phone. Calls can be routed to an Announcement application or to an Exchange Unified Messaging (UM) server.

How you configure the unassigned number table depends on how you want to use it. You can configure the table with all the valid extensions for your organization, with only unassigned extensions, or with a combination of both types of numbers. The unassigned number table can include both assigned and unassigned numbers, but it is invoked only when a caller dials a number that is not currently assigned. If you include all the valid extensions in the unassigned number table, you can specify the action that occurs whenever someone leaves your organization, without needing to reconfigure the table. If you include unassigned extensions in the table, you can tailor the action that occurs for specific numbers. For example, if you change the extension for your customer service desk, you can include the old customer service number in the table and assign it to an announcement that provides the new number.

Before you configure the unassigned number table, you must have already either defined one or more announcements or set up an Exchange Unified Messaging (UM) Auto Attendant. To create a new announcement, run the New-CsAnnouncement cmdlet. For details, see New-CsAnnouncement in the Lync Server Management Shell documentation. To see if you have configured Exchange UM settings, run the Get-CsExUmContact cmdlet. For details, see Get-CsExUmContact in the Lync Server Management Shell documentation.
