Unable to graduate our app because of the Call Control permission

When request for such a thing, remember to provide the app client id.

In the future, you can any API that requires the permission that you need for your notification. For example, your app is listing to telephony session event notifications and it requires the Call Control permission, test your app by making inbound calls to detect call events, then implement an extra function to just forward those incoming call to another number. That way your app will exercise the Call Control permission when it call the call forward API. Remove that function from your code after testing and graduating your app.

Done.

I agree with you that the requirement in this case should be removed, and we are in the process to improve the app graduation experience.

However, I don't think that the recommended workaround solution is a "way more code" to meet the requirement. Look at the extra code e.g. in Node JS.

// incoming telephony event
  var body = msg.body
  if (body.parties[0].direction == "Inbound" &&
        body.parties[0].status.code == "Proceeding"){
        forwardCall(body, "+1650XXXYYYY")
  }

async function forwardCall(call, toNumber){
  var endpoint = '/restapi/v1.0/account/~/telephony/sessions/'
  endpoint += call.telephonySessionId
  endpoint += `/parties/${call.parties[0].id}/forward`
  try{
    var resp = await platform.post(endpoint, { phoneNumber:toNumber })
    var jsonObj = await resp.json()
    console.log(JSON.stringify(jsonObj))
  }catch(e){
    console.log(e.message)
  }
}
