Outbound calling
Cancel Call Task
Cancels a call task so that it is not called.
Returns a 200 OK response with canceled: true when the task was still waiting to be called, and canceled: false when it had already reached a terminal status, in which case the request is a no-op.
When a call is already under way the cancellation cannot take effect immediately: the endpoint returns a 202 Accepted response with cancel_requested: true, the call in progress runs its course, and no further call is placed.
