Abstract

Embodiments provide for a system and method that address challenges associated with audio routing of an incoming call between two devices operatively coupled via a short-range wireless connection. Ultrasonic watermark signals are generated and sent between the two devices. Detection and non-detection of the ultrasonic watermark signals controls the audio routing. The ultrasonic watermark signals can be modified based on a predetermined operational characteristic known only to the two devices for increased robustness to the system.
