Hello Nicola,
To have Vapi decline a call, you would typically need to configure your webhook or the logic on make.com to respond with a specific command or status code that indicates to Vapi that the call should not be answered. Since Vapi does not yet have the capability to hang up the phone at the end of the call, you would need to handle this within your current setup.
If you want Vapi to close the line without answering, you should return a response that instructs Vapi not to proceed with the call. This could be a specific HTTP status code or a payload that your Vapi setup recognizes as a command to reject the call.
However, without specific documentation or details on how Vapi handles incoming call instructions, I cannot provide you with an exact response format. You may need to refer to the Vapi documentation or contact their support to get the precise information on how to format your response to decline a call.
If you have any further questions or need assistance with another matter, feel free to ask.
