Our alerts use audile enunciate tones with the alerts. If our users are currently on a phone call, and an alert is send to their device, the alert is enunciated very loudly into their ear. For example, the user could be holding the phone up to their ear during a call, and the phone will loudly alert "Bed Exit" right into their ear. Our idea would be for the alert tone to adjust and decrease when a user is on a call.
