### Answer --- Components themselves only have an "Exit Component" node, which returns control to the main flow rather than ending the call. [(1) ]() To end a call from within a component, you have two options: 1. Use an End Call function inside the component — Components can include function nodes and use your configured tools, including the

end_call

tool. Define the tool within the component (tools defined in components are not visible at the agent level) . 2. Route back to the main flow and use an End Node there — Have your component's Exit node transition to an End Node in your main Conversation Flow that triggers the call hangup. [(2) ]() If you're using function calling, make sure to define

end_call

, have the model choose it, and send

end_call: true

.
