Currently, our system does not provide an endpoint to directly end a call via an API request. However, you can control the call flow and end the call from within your voice application logic. If you need to end a call programmatically from your server, you would typically instruct your voice application to hang up as part of the call logic when a certain condition is met.
If you require further assistance on how to configure your voice application to end a call or if you have any other questions, please ask support for more info on this.
