Restricts the numbers the users can use to create alternate extensions for themselves through interfaces such as the Cisco Personal Communications Assistant or via an API call. Also restricts numbers from being offered as alternate extensions. For example, you might block a lobby or conference room extension so that users who frequently call Unity Connection from those shared phones are not automatically prompted to add the number as an alternate extension. User-Defined and Automatically-Added Alternate Extensions Restricts numbers from being offered as alternate extensions. For example, you might add a lobby or conference room extension so that users who frequently call Unity Connection from those shared phones are not automatically prompted to add the number as an alternate extension. Excluded Extensions for Automatically Added Alternate Extensions Configuring Restriction Tables You can edit the predefined restriction tables, and you can create up to 100 new ones. You can also add up to 50 dial strings to a table. New dial strings are automatically inserted into the restriction table as Dial String 0. Note that the order of the dial strings is very important because Unity Connection sequentially compares a phone number to the call patterns in the restriction table, starting with Dial String 0. If a number matches more than one call pattern, the number is handled according to the first call pattern it matches. You can indicate call patterns by entering specific numbers or using the following special characters as wildcards: Matches zero or more alphanumeric strings. * Matches exactly one digit or character. Use? as a placeholder for a single digit. ? Corresponds to the # key on the phone.

By default, all restriction tables have * as the call pattern in the last dial string of the table. You cannot edit this call pattern setting, as it prevents a case in which the entered number does not match any call pattern in the table. However, you can change the Blocked field setting for this dial string to either permit or restrict a number. Procedure Step 1 In Cisco Unity Connection Administration, expand System Settings > and select Restriction Tables. The Search Restriction Tables page displays the currently configured restriction tables. Step 2 Configure a restriction table (For information on each field, see Help> This Page): • To add a restriction table: On the Search Restriction Tables page, select Add New. On the New Restriction Table page, enter the values of the required fields. On the Edit Restriction Table page, add patterns to the restriction table and select Save. • To edit a restriction table: System Administration Guide 107 Call Management Configuring Restriction Tables
