# Press Digit (IVR Navigation)

> Enable your agent to navigate DTMF-based IVR phone menus by pressing digits.

## Overview

The Press Digit tool lets your agent send DTMF tones to navigate IVR systems — useful for outbound calls where your agent needs to get through a phone menu before reaching a person or department.

***

## Setup

<Steps>
  <Step title="Add the tool">
    In your agent's Functions section, select **Press Digit** from the dropdown. Optionally add a description specifying when and what digits to press.
  </Step>

  <Step title="Write navigation prompts">
    Give the agent clear instructions for navigating the IVR. Two approaches:

    **Goal-based** (when you don't know the exact sequence):

    ```txt theme={null}
    Navigate the IVR to reach the scheduling department.
    Preferred keywords: scheduling, appointments, new patients.
    Avoid: billing, referrals.
    ```

    **Direct** (when you know the exact path):

    ```txt theme={null}
    Press 1 for English, then press 2 for appointments.
    ```
  </Step>

  <Step title="Define edge case rules">
    Handle unexpected situations explicitly:

    ```txt theme={null}
    If the IVR indicates you have reached the wrong company, immediately call end_call.
    ```
  </Step>

  <Step title="Optionally extract post-call data">
    Track IVR metrics like:

    * Whether an IVR was encountered
    * Whether a human was reached
    * Navigation path taken
    * Number of retries
  </Step>

  <Step title="Test">
    Place actual outbound calls to the IVR system, or simulate one by speaking IVR-style prompts during a test call.
  </Step>
</Steps>

<Note>
  Where the IVR accepts speech, use spoken responses. Only use digit-pressing when the system requires numeric input.
