# Control flow: Close The **Control Flow: Close** node will effectively end the conversation. It cannot be opened again. Any new interaction with this user will result in a new conversation being created, triggering the `__main__` dialog again. On the [Phone channel](/studio/channels/phone.md), the text of the **Control flow: Close** node will be spoken to the user, and the conversation will be closed. On text based channels, it hides the chat input, and/or shows a control that indicates that the conversation is over. On channels that do not support any close controls, but are "single conversation", e.g. WhatsApp, Facebook Messenger, etc, the next time a user starts chatting, a new conversation is opened. {% hint style="info" %} The **Control Flow: Close** node will trigger the system dialog `__closed__` to be triggered. By creating a flow with an entry node that is triggered by **closed**, you can influence what happens at closure. {% endhint %} ## Resources * [Phone](/studio/channels/phone.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
