Use the EAC to configure the group of users that Outlook Voice Access users can contact

  1. In the EAC, navigate to Unified Messaging > UM dial plans.

  2. In the list view, select the UM dial plan you want to modify, and then click Edit Edit icon..

  3. On the UM dial plan page, click Configure.

  4. In Transfer & search, under Allow callers to search for users by name or alias, select one of the following options:

    • In this dial plan only: Use this option to allow Outlook Voice Access users who call in to an Outlook Voice Access number to locate and contact users who are within the same dial plan.

    • In the entire organization: Use this option to allow Outlook Voice Access users who call in to an Outlook Voice Access number to locate and contact anyone in the entire organization. This includes all users who are mailbox-enabled.

    • Only on this auto attendant: Use this option to allow Outlook Voice Access users who call in to an Outlook Voice Access number to connect to a specific auto attendant. You must create the auto attendant before you specify it here. This allows Outlook Voice Access users to be transferred to another auto attendant. The auto attendant you choose here can be a speech-enabled or non-speech-enabled auto attendant.

    • Only for this extension: Use this option to allow Outlook Voice Access users to connect to an extension number that you specify. You can use only numeric digits for the extension. The number of digits that you define in this field must match the number of digits in the extension numbers that are configured on the UM dial plan.

  5. Click Save.
