Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1

Use the Dialing Restrictions tab on the Unified Messaging (UM) auto attendant properties to configure dialing rules for callers that call in to a UM auto attendant. An auto attendant is the collection of voice prompts that callers hear instead of a human operator when they call in to an organization that has Exchange 2007 Unified Messaging. You can use these settings to control the extension numbers that can be reached from an auto attendant or control the telephone numbers that can be dialed by callers that have dialed into the auto attendant.

  • Allow calls to users within the same dial plan

    • Select this check box to allow users who call in to an auto attendant to place or transfer calls to an extension number that is associated with a UM-enabled user who is associated with the same dial plan as the auto attendant. By default, this setting is enabled.

    • When you disable this setting, users who call in to an auto attendant will be able to place or transfer calls to any non UM-enabled users or other extension numbers that are not associated with a UM-enabled user but will be unable to transfer calls to UM-enabled users who are associated with the same dial plan as the auto attendant. This is because the Allow calls to extensions setting is enabled by default.

  • Allow calls to extensions

    • When this setting is disabled, users who call in to an auto attendant cannot place calls to non UM-enabled users or other extension numbers that are not associated with a UM-enabled user. However, they can place calls or transfer to extension numbers that are associated with UM-enabled users. This is because the Allow calls to users within the same dial plan setting is enabled by default. The Allow calls to extensions setting is enabled by default.

    • When this setting is enabled, users who call in to an auto attendant can place calls to non UM-enabled users, other extension numbers that are not associated with a UM-enabled user, and UM-enabled users. This is because the Allow calls to users within the same dial plan setting is enabled by default.

    • You can enable this setting in an environment where not all users have been UM-enabled. This setting is also useful when you want to allow users who call in to a telephone number that is configured on an auto attendant to call extension numbers that are not associated with a UM-enabled user.

  • Select allowed in-country/region rule groups from dial plan

    • Use this section to add or remove allowed in-country/region dialing rule groups. By default, there are no in-country/region dialing rule groups configured on UM auto attendants.

    • In-country/region dialing rule groups are used to allow or restrict the telephone numbers within a country or region that any user who has dialed in to the UM auto attendant can dial. This helps prevent unnecessary or unauthorized telephone calls and charges.

    • To add in-country/region dialing rule groups, you must first create the appropriate in-country/region dialing rule groups on the dial plan that is associated with the UM auto attendant, and then add the appropriate dialing rule entries on the dialing rule group. After you have created the required dialing rule groups on the dial plan, you must then add the dialing rule groups to the list of dialing restrictions on the Dialing Restrictions tab on the UM auto attendant.

    • In-country/region dialing rule groups can be used to enable a Unified Messaging server to allow or restrict access to telephone numbers within a country or region. This is applied to any user who has called in to an auto attendant.

  • Select allowed international rule groups from dial plan

    • Use this section to add or remove allowed international dialing rule groups. By default, there are no international dialing rule groups configured on UM auto attendants.

    • International dialing rule groups are used to allow or restrict the telephone numbers outside a country or region that any user who has dialed in to the UM auto attendant can dial. This helps prevent unnecessary or unauthorized telephone calls and charges.

    • To add international dialing rule groups, you must first create the appropriate international dialing rule groups on the dial plan that is associated with the UM auto attendant, and then add the appropriate dialing rule entries on the dialing rule group. After you have created the required dialing rule groups on the dial plan, you must then add the dialing rule groups to the list of dialing restrictions on the Dialing Restrictions tab on the UM auto attendant.

    • International dialing rule groups can be used to enable a Unified Messaging server to allow or restrict access to telephone numbers outside a country or region. This is applied to any user who has called in to an auto attendant.
