Twilio voice alarms: option to skip the "press any key" challenge

Ignition 8.3, Twilio Voice notification profile.

With Require PIN Authentication = false, calls still play the Non-PIN Challenge ("press any key to continue") before reading the alarm, and there's no setting to skip it.

Our on-call contractors may be drowsy when answering at night and need to hear the alarm straight away, but we still would require alarm acknowledgement at the end of the phone call.

Request: a "no challenge" option that reads the alarm as soon as the call is answered and still allows "press 1 to acknowledge".
