End Call

Overview

The End Call action lets your AI Voice Agent intentionally end a call at the right moment. You can control when the call should end, whether the agent says a goodbye, and what that goodbye sounds like.

To ensure consistent behavior, you must also instruct the agent in its prompt when this action should be invoked.

Configure the End Call Action

When adding an End Call action, configure the following fields.

Name of End Call Action

A unique identifier for the action (for example, end_call). This is the function name the agent will invoke.

End Call Description

Describe when the AI Agent should use this action to end a call. This guidance helps the model determine the correct moment to hang up.

Example:

Invoke this action when the contact confirms they are not interested, says “goodbye,” or indicates the conversation is complete.

Skip Goodbye Message

Enable Skip Goodbye Message to have the agent hang up immediately without saying anything.

This is useful for:

Voicemail or answering machine scenarios where you want to hang up without leaving a message,
Situations where speed and efficiency matter more than graceful goodbyes.

When this toggle is enabled, the agent will end the call as soon as the action is invoked.

Goodbye Message Prompt

Use the Goodbye Message Prompt to control what the agent says right before ending the call.

If a prompt is provided, the agent use the prompt to generate a goodbye message,
If left empty, the agent will generate a goodbye message using its main prompt.

Update Your Agent Prompt

Your agent prompt should clearly specify when the End Call action should be used. Without explicit guidance, the agent may hesitate or end calls inconsistently.

You can include these instructions in:

Task Steps
Questions and Objections Handling
Action Nodes (in Multi-State Agents)

Example

4. Ask "Are you ready to move forward?"

- If the contact responds yes, explain the next steps.
- If the contact responds no, call end_call and say "Thanks for your time."
