## Configure Voicemail Detection
After enabling voicemail detection (for both Simple Agents and Workflows), you'll need to configure how it behaves:
### Action
Choose what happens when voicemail is detected:
The agent will immediately end the call when voicemail is detected without leaving a message.
**Best for:**
* When you only want to reach live contacts
* Compliance requirements that restrict automated voicemail messages
* High-volume calling campaigns
The agent will deliver a custom voicemail message when voicemail is detected.
**Best for:**
* Ensuring your communication reaches the recipient
* Appointment reminders and follow-ups
* Customer service callbacks
* Sales and lead nurturing
***
### Voicemail Message
If you selected "Leave a message if reaching voicemail", configure your message:
Use dynamic, AI-generated messages based on the conversation context and agent's prompt instructions.
**How it works:**
* The AI composes the voicemail message on the fly
* Can adapt based on conversation history
* More natural and contextual
**Example use case:** "Generate a voicemail explaining why I called based on the customer's recent support ticket."
Use a fixed, pre-written message that will be delivered every time.
**How it works:**
* Type your exact message in the text field
* The same message is used for every voicemail
* Consistent and predictable
**Example:**
```
Hey, sorry we could not reach you directly. Please give us a callback if you can.
```
Keep voicemail messages brief (20-30 seconds) and include a clear call-to-action with your callback number or next steps.
***
### Save Configuration
Click **Save** to apply your voicemail detection configuration.
For workflows, remember to also click **Save** on the workflow editor after configuring voicemail detection.
***
## Best Practices
* Aim for 20-30 seconds maximum
* State your name and company clearly
* Provide a clear call-to-action
* Include a callback number or next step
* Call the agent yourself and let it go to voicemail
* Test with different voicemail systems (mobile, landline)
* Verify the message is complete and sounds natural
* Check that the right action (hang up or leave message) is triggered
* **Hang up** for high-volume outbound campaigns where you only need live conversations
* **Leave message** for important communications like appointment reminders, follow-ups, or customer service
* Use conversational language
* Avoid complex terminology or long sentences
* Read the message aloud to check if it sounds natural
* Include specific information (reason for call, action needed)
