The request asks what to use for a Call Control API, and it is ambiguous: the name "Call Control" matches Callcontrol 2, a call-blocking service with a documented API, but the request does not say what the call control should do (block spam calls, place or route calls, or control a telephony platform). Twilio 1 is the established platform for programmatic voice and call control, with an SDK and a custom API call action.
A question back: Do you want to block or screen incoming calls (for example spam), or to place, route and control live calls in your own application?
