title: End Call
description: "Lets the agent hang up by itself once the conversation is complete, with a closing line it says first. When to add it, and what it costs."

<Badge variant="accent">Voice agents</Badge>

**End Call** lets the agent end the phone call when the conversation is complete.
Without it the agent waits for the caller to hang up, or for the silence and
duration limits under **Advanced** to cut the call.

:::tip[Every voice agent should have it]
An agent that cannot hang up keeps a line open after a goodbye, which costs minutes
and leaves a dangling call in the logs. Add **End Call** to every voice agent and
tell it in **Tasks** when the call is over.

![The End Call form.](/media/build/end-call-form.webp)

## Configuring it

Open **Tools** under **Build**, choose **Add tool**, then **End Call**. The form has
only the [shared fields](/build/tools/overview#fields-every-tool-shares); the
defaults are below.

| Field | Default | Notes |
|---|---|---|
| **Tool Title** | `End Call` | Its ID, `end_call`, is shown under the field. |
| **Description** | `Ends the phone call when the conversation is complete` | Add the cases: `…or when the caller says goodbye, or asks to stop`. |
| **AI Response** | `Thank you for calling. Have a great day!` | Said before the line drops. Keep it one sentence; the call ends as soon as it is spoken. |

Choose **Add Tool**, then **Save** the agent.

## Behaviour and limits

- The agent says **AI Response**, then the call terminates and the recording,
  transcript and outcomes are processed as usual.
- The agent decides when to call it from the **Description** and the conversation.
  If it hangs up too early, narrow the description: `Only after the caller confirms
  they have nothing else`.
- In a flow agent, an **End Call** node does the same job at a fixed point in the
  flow. Add the tool as a global tool when the agent should also be able to hang up
  from the middle of a stage. See [Nodes](/build/flow-agents/nodes#end-call).
- Calls ended by the tool show the agent as the party that hung up in the call's
  disconnect reason. See [Call details](/operate/call-details).
