You can configure input conditions, success routing, timeout handling, and error handling. ## Configure the Node ### General Settings In **General Settings**, configure the following: General Settings * **Custom Name**: Enter a name to identify the node. * **Your Message to User**: Select a message type under **Choose your message type**: * **Text to Speech**: Type or select a message to convert to speech. Click **+ Create New** to add a new prompt, or **+ Add Another** to define multiple messages (one is randomly selected at runtime). Text to Speech * **Audio File**: Type a message or click **+ Upload New** to upload an .mp3 or .wav file. Audio File * **Link**: Click **+ Create New** to add message text and an audio file URL (.mp3 or .wav). Click **+ Add Another** for additional URLs. Link ### Condition Click the **Condition** icon to define the criteria for accepting input: * **Maximum length of digit**: Enter the maximum number of digits the caller can input. * **Ending Keypress**: Enter the key that signals the end of input (for example, **#**). * **On success**: Select a **Go to node** to route the flow when the condition is satisfied. Condition ### Timeout Configure the timeout flow with the following fields: 1. **Timeout**: Enter the wait time in seconds before a timeout event occurs. * **Your Message to User**: Select a message type (Text to Speech, Link, or Audio) to play when a timeout occurs. See [General Settings](#general-settings) for details. 2. **Advanced Control**: * **Number of Tries**: Enter the maximum number of retries allowed. * **Action after Exceeding Retries**: Select the node to route to after retries are exhausted. Timeout ### Wrong Input Use this tab to configure the flow when a caller provides incorrect digit input. 1. **Your Message to User**: Select a message type (Text to Speech, Link, or Audio) to play. See [General Settings](#general-settings) for details. 2. **Advanced Control** > **Number of Tries**: Enter the maximum number of retries for correct input. 3. **Advanced Control** > **Action after Exceeding Retries**: Select the node to route to after retries are exhausted. Wrong Input ### Error Handling Error handling is available under the **Wrong Input** tab. Use it to define how system errors are handled during a call. * **Your Message to User**: Select a message type (Text to Speech, Link, or Audio) to play when a system error occurs. See [General Settings](#general-settings) for details. * **Go to node**: Select the node for error handling. You can create a new node or select an existing one. Error Handling ### Store Digit Input After the caller keys in their input, Contact Center AI stores it as a variable in a Script Task node. The context variable syntax is: ``` Context.steps.<< context_node_name >> ``` For example: ``` context.steps.IVRDigitInput ``` To store input from this node in a Script Task: 1. Add a **Script Task** node below the IVR Digit Input node. 2. In **General Settings** > **Define a Script**, add the step reference (for example, `steps.IVRDigitInput`). Script Task
