1. In the EAC, navigate to Unified Messaging > UM dial plans. In the list view, select the UM dial plan you want to change, and then click Edit .
   
   
2. On the UM Dial Plan page, under UM Auto Attendants, select the UM auto attendant for which you want to create a non-business hours navigation menu. On the toolbar, click Edit .
   
   
3. On the UM Auto Attendant page, click Menu navigation, under Non-business hours menu navigation, select Enable non-business hours menu navigation, and then click Add .
   
   
4. On the New menu navigation entry page, use the following options to create a new menu navigation entry:
   
   
   • Prompt   Use this box to type the name of the new navigation menu. The navigation menu name is used for display purposes only. This is a required field.
     
     Because you may want to specify multiple new navigation menus, we recommend that you use meaningful names for your key mappings. The maximum length of the name for the key mapping is 64 characters, and it can include spaces. However, it can't include any of the following characters: " / \ [ ] : ; | = , + * ? < >.
     
     
   • When this key is pressed   Use this list to enable key mapping. The key mapping is the number key that a caller presses to have the auto attendant perform a specific operation, for example, forwarding the caller to another auto attendant or to an operator. By default, no entries are defined.
     
     Use the drop down list to select the numeric key (from 1 through 9) that the caller must press. Zero (0) is reserved for the auto attendant operator.
     
     If you select Time Out from the drop down list, it enables callers to be transferred to an extension number or to another auto attendant if they don't press a key on the telephone keypad. For example, "Please stay on the line and your call will be answered by the next available representative." The default setting is 5 seconds. If you enable this option, a blank key mapping will be created.
     
     
   • Play the following audio file   Use this option to select a previously recorded audio file for callers. Click Change, and then click Browse to locate the audio file. If you leave the audio file as the default <None>, the Unified Messaging TTS (Text to Speech) engine will synthesize a non-business hours main menu prompt. Alternatively, you can create a customized audio file that can be used for the non-business hours main menu prompt for a speech-enabled auto attendant that would say, for example, "You have reached Contoso during non-business hours. To leave a voice message for sales, say 1. To leave a voice message for technical support, say 2. To leave a voice message for administration, say 3. To reach an after hours operator, press zero."
     
     
   • Perform this additional action   Select one of the following options to define the action that you want the auto attendant to perform for the caller:
     
     
     • None   If you don’t want the auto attendant to transfer the call to an extension or to another auto attendant, or leave a message for a user, use this option.
       
       
     • Transfer to this extension   Select this option to enable calls to be transferred to an extension number. If you enable this option, use the box to type the extension number where the call will be transferred. This field allows only numeric characters. It can't include any of the following characters: " / \ [ ] : ; | = , + * ? < >.
       
       
     • Transfer to this UM auto attendant   Select this option to transfer the call to an existing auto attendant. Click Browse to locate the auto attendant that you want to use. Before you enable this option, you must first create and configure the auto attendant. This option is used when you create a parent/child structure of UM auto attendants.
       
       
     • Leave a voice message for this user   Select this option to enable a caller to leave a voice mail message for a user that's on the same dial plan as the UM auto attendant that you're configuring. When a caller chooses this option from an auto attendant menu, they'll be prompted to leave a voice message for the user that was selected. Click Browse to locate the UM-enabled user.
       
       
     • Announce business location   Select this option to enable a caller to choose an auto attendant menu option and hear the location of the business that's configured on the UM auto attendant. To enable this to work correctly, you must first enter the business location in the Business location box on the General page on the UM auto attendant.
       
       
     • Announce business hours   Select this option to enable a caller to choose an auto attendant menu option and hear the hours of operation for the business that's configured on the UM auto attendant. To enable this to work correctly, you must first configure the business hours on the Business hours page on the UM auto attendant.
       
       
5. Click OK to create the new menu navigation.
   
   
6. On the UM Auto Attendant page, click Save to save your changes.
   
   

This example configures a UM auto attendant named MyAutoAttendant and enables non-business hours key mappings so that when callers say "After Hours" they will be forwarded to extension number 12345, and if they say "Directions" they will be forwarded to extension number 23456.
