# Conversation Settings - Voicemail Detection 📬

Voicemail Detection is mission-critical for ensuring your agent behaves correctly when a user doesn't pick up. Basically, this tool stops your agent from having a deep conversation with a recording—which acts as a great fail-safe.\
\
We highly recommend keeping this toggled ON to ensure maximum call efficiency.

To access it, go to your voice agent and hit Settings > Call Settings.

Once enabled, you can choose between two main behaviors when a mailbox is detected:

* **Hang up immediately:** The system terminates the call the second it hits voicemail.
* **Leave a message:** The agent leaves a voicemail. You have two configuration paths here:
  * **Static Phrase:** A fixed script the agent reads every single time. Simple, reliable.
  * **Prompt:** Dynamic instructions based on business rules. This is the smart option—it allows you to vary the message based on context (e.g., asking for a call back to a specific number or checking meeting availability depending on the greeting).
