# Voicemail Detection In DialNexa

> Understand DialNexa voicemail detection, voicemail messages, hangup behavior, and dynamic variables in voicemail messages.

DialNexa voicemail detection controls what happens when an outbound call reaches voicemail instead of a person. The call settings panel supports voicemail detection, hangup behavior, and voicemail messages that can include dynamic variables.

<Tip>
  Voicemail is not a failed conversation if your campaign planned for it. It is only chaos when nobody decided what should happen.

## What Voicemail Detection Supports

DialNexa voicemail detection recognizes some automated call paths and applies your hangup or leave-message settings. It does not treat every device that can record a message the same way.

| Supported           | What it looks like                                                     | Example                                                                               |
| ------------------- | ---------------------------------------------------------------------- | ------------------------------------------------------------------------------------- |
| Voicemail detection | A carrier or mobile voicemail greeting after the call is not answered. | "The person you are calling is not available. Please leave a message after the tone." |
| IVR detection       | An automated phone menu before a person or voicemail picks up.         | "Thank you for calling Metro Clinic. Press 1 for appointments."                       |

| Not supported      | What it looks like                                                               | Example                                                                                                                                            |
| ------------------ | -------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- |
| Answering machines | A standalone answering device that picks up on its own with a recorded greeting. | A home or office machine that answers on the first ring and says, "Hi, you've reached the Smith residence. Please state your reason for the call." |

<Note>
  If a call reaches an answering machine, DialNexa may not classify it as voicemail. Test numbers from your target list before you launch a batch campaign.
</Note>

## Voicemail Options

Voicemail behavior is configured per agent version.

| Option                                | Behavior                                                                           |
| ------------------------------------- | ---------------------------------------------------------------------------------- |
| Voicemail Detection                   | Turns voicemail handling on or off.                                                |
| Hang up if reaching voicemail         | Ends the call when voicemail is detected.                                          |
| Leave a message if reaching voicemail | Speaks the configured voicemail message instead of hanging up.                     |
| Voicemail message                     | Text the agent should leave. It can include placeholders such as `{{first_name}}`. |

## Prepare Voicemail For A Campaign

<Steps>
  <Step title="Decide whether voicemail is useful">
    For some reminders, leaving a short message is useful. For other use cases, hanging up is cleaner.
  </Step>

  <Step title="Keep the message short">
    Voicemail should identify the reason for the call without sounding like a full script.
  </Step>

  <Step title="Check variables">
    Add fallback values for every placeholder used in the voicemail message.
  </Step>

  <Step title="Test with a voicemail inbox">
    Confirm the message sounds natural when recorded.
  </Step>
</Steps>
