Customize the default callback topics as per your requirements.

## Vorbereitungen

Role required: admin

## Warum und wann dieser Vorgang ausgeführt wird

You can customize one of the following default callback topics: Callback-Phone for
voice channels and Callback-General for messaging or chat channels. The following
procedure explains how to customize the Callback-Phone topic.

## Prozedur

1. Duplicate the Callback-Phone topic from the Virtual Agent Designer.  
   For more information on how to duplicate a topic, see [Duplicate a Virtual
   Agent topic](https://servicenow-prod.fluidtopics.net/PFQ9~sp9KYQNkIJPDQa_jA "Create a new topic or topic block by copying an existing Virtual Agent topic or topic block and customize it.").
2. In the Advanced properties section of the Properties tab, select the voice channel that you want to associate with the custom callback topic.
3. On the Flow tab, modify the default callback flow and set the following properties in the Script action utility, if required.
   1. Set Global Callback Executed (vaVars.global_callback_executed) to true.
   2. Set No Agent Available (vaVars.global_show_no_agent_available_msg) to false.
   3. Set the following properties in the Create Callback Task node.  
      * Set Global Callback Executed (vaVars.global_callback_executed) to true.
      * Set No Agent Available (vaVars.global_show_no_agent_available_msg) to false.
      * Callback Number (callback_number): Required field to be populated with the number on which the user requested a callback. This number may be the number that the user is calling from or the dialed number.
      * Short description (short_description): User issue description.
      * Initial Interaction (initial_interaction): Interaction detail from which the callback task has been initiated.
      * Max Retry Attempts (max_retry_Attempts): Maximum retry attempts after which the callback task is closed.
      * Expire Time (expire_time): Callback timeout after which the callback task is closed.
      * Messaging Channel (messaging_channel): Messaging channels configured for use. If not provided, the default callback channel is used.
      * Scheduled (scheduled): Set to true to make the callback task eligible for auto callback.
