The PTT handler was muting the audio source before checking if a PTT device was configured. This prevented kiosks from sending audio back to calling phones during normal intercom operation. Changes: - Move audio mute command after PTT device check - Only mute audio when PTT device is actually configured - Leave audio unmuted for standard kiosk intercom functionality - Add clarifying comments about PTT mode vs normal operation This fixes the issue where phones calling the kiosk could send audio but received no audio back from the kiosk.
