# End call

> Tell your assistant when it may hang up: clear rules for ending calls only after the goal is met or the caller is done.

The **End call** tool lets you give the assistant a **rule set for when it may disconnect** from its side. You enable it under **Prompt & Tools** in the **Standard tools** section, then fill in **when** hanging up is allowed.

<div style={{ position: "relative", paddingBottom: "56.25%", height: 0 }}>
  <iframe style={{ position: "absolute", top: 0, left: 0, width: "100%", height: "100%", border: 0 }} src="https://www.tella.tv/video/anruf-beenden-tool-funktion-einrichtung-erklart-4a4w/embed?b=0&title=0&a=1&loop=0&t=0&muted=0&wt=0&o=1" allowFullScreen allowTransparency />
</div>

## Set it up

1. Open the assistant → **Prompt & Tools**.
2. In **Standard tools**, turn on **End call** so the tool is selected (highlighted).
3. A configuration panel opens below.
4. In the **when the assistant may end the call** field, describe the conditions in **as much detail as possible** — the clearer your rules, the more reliably the behavior matches what you want.

## What to write

You are defining **under which circumstances the AI is allowed to hang up**. Examples:

* **Simple:** End the call when all questions are answered and the caller no longer needs help.
* **More detailed:** Also allow ending when an appointment was successfully booked, when the caller clearly says goodbye, or when the conversation is clearly finished.

Cover **as many realistic cases as you can** (success paths, goodbyes, “nothing else needed”) so the model does not end too early or too late.

### Tip on wording

Many teams draft and refine these rules with an LLM (for example Claude or ChatGPT): describe your process in plain language and ask for a tight checklist-style instruction you can paste into the tool field.

  Need a whole toolset instead of building HTTP actions one by one? Connect an external **MCP server** — tools are discovered automatically. See [MCP Servers](/en/platform/mcp-servers).
