Use the General tab to configure the dial plan settings for Unified Messaging (UM). For example, you can configure UM dial plan settings to include the voice message originator e-mail address, send non-delivery reports, and enable users who are associated with the dial plan to receive faxes. The settings that you configure on the UM dial plan will affect all users who are associated with the dial plan.

Associated servers
  • This section displays the Unified Messaging servers that are associated with a dial plan. The UM servers that are listed in this section process incoming calls for users who are associated with the dial plan.

  • UM servers can be associated with single or multiple dial plans. You must use the UM Server Settings properties tab in the UM server's properties to add a UM server to a dial plan.

Associated UM IP gateways
  • This section displays the UM IP gateways that are associated with a dial plan. The UM IP gateways that are listed in this section process incoming calls for users who are associated with the dial plan.

  • A UM hunt group establishes a link between a UM dial plan and a UM IP gateway and can also be associated with a dial plan by first being associated with a UM IP gateway.

  • You can associate a UM IP gateway with a dial plan when you create a UM hunt group.

Number of digits in extension
  • Use this text box to specify the number of digits in the extension numbers for users who are associated with this dial plan. For example, if a user associated with a dial plan dials a 4-digit extension to call another user in the same dial plan, select 4 as the number of digits in the extension.

  • The number of digits for extension numbers is based on the telephony dial plan that is created on a Private Branch eXchange (PBX). This is a required field that has a value range from 1 to 20. The typical extension length is from 3 to 7 digits.

  • If your existing telephony environment includes extension numbers, you should specify a number of digits that matches the number of digits in those extensions.

Send a non-delivery report if message delivery fails
  • Select this check box to allow a non-delivery report (NDR) to be sent if the voice message could not be delivered.

  • If you enable this option an NDR will not be sent until you associate the 'Microsoft Exchange' recipient with a mailbox. To associate the 'Microsoft Exchange' recipient to a mailbox, see Set-OrganizationConfig (RTM).

  • By default, this option is disabled.

Allow users to receive faxes
  • Select this check box to allow fax messages to be received by users who are associated with the dial plan.

  • If you do not select this check box, all users who are associated with the dial plan will be unable to receive fax messages in their Inbox.

  • By default, this setting is enabled.

After you configure the options on this tab, click Apply to accept the changes.
