📘Digit Block

Overview

The Digit block is a Voice Router–specific block that allows users to interact during a call using:

  • Keypad input (DTMF)

  • Voice responses

It is designed to create numbered voice menus, enabling users to select an option either by pressing a key or by speaking.

Interface

In the Indigo interface, the Digit block includes the following elements:

Message

The text that is read aloud to the user via text-to-speech (TTS).

It typically presents the available options in a numbered format.

Example:

“Press 1 for Sales, 2 for Support”

Keypad options

A list of selectable options that define the structure of the voice menu.

Each option includes:

  • Button label: the numeric key the user presses (e.g. “1”, “2”, “3”)

  • Connect: defines where the flow continues after selection:

    • another agent

    • a workflow

  • Variables: allows assigning a value to a variable when the option is selected

You can add or remove options as needed (minimum: 1).

No match

A dedicated configuration button used to define the fallback behavior. From here, you can connect:

  • a variable

  • another agent

  • a workflow

This option is used when the user input does not match any of the defined keypad options.

Notes:

  • It is always required

  • It cannot be removed

When to use it

Use the Digit block when you need to create a structured voice menu where users can:

  • Choose between multiple options during a call

  • Interact using keypad input (DTMF) or voice

  • Be routed to different flows, agents, or variables based on their selection

Typical use cases include:

  • IVR menus (e.g. Sales, Support, Information)

  • Call routing and triage

  • Guided user journeys over voice channels
