Deficient SOP for, enforcement, usage, or configuration of the auto-answer feature.

In the event the auto-answer feature is approved for use or cannot be administratively disabled and thus is available for users to activate, several mitigating requirements must be met. The first of these is that the user(s) to which the feature is available must be trained in its proper use and in the vulnerabilities it presents because the user is the one that must implement the operational mitigations. The second is the VTU must answer the call with the microphone muted and with the camera covered or disabled. This will prevent an ongoing conversation from being heard and room activities seen by the caller. This will also prevent the room from being audibly and visually monitored if a call is automatically answered when the VTU is un-attended. The third mitigating requirement is that the user must be notified that the VTU has received and answered a call such that the user may be viewed if the camera is not/cannot be covered or listened to if the microphone is not/cannot be muted. This means that a noticeable visual indication must be provided and any available audible signal must be maintained at an audible level so that it can be heard.
