VAPI Example Cockpit

A cockpit to view and control the current activity of VAPI voice agents. This cockpit is all about outbound agents, which are much more complicated than inbound agents (e. g. support bots).

This is a minimal solution to demonstrate the usage of VAPI API endpoints:

Required: An Outbound Phone Number

To be able to schedule alls you need to have an outbound phone number set up in VAPI. Phone calling requires the consent of the called person in most countries - expect some compliance work before you are able to use such a number! VAPI as of 2025 does not provied outbound numbers you have to resort to twilio.com or similar providers.
