Is there a Cisco Proximity Configuration guide that covers the required network configuration, what ports its uses, specifically what information is advertised over the "ultrasonic audio" signal the app uses to discover the codec, etc? Trying to work with my Network team to get the correct ports opened us between the VLAN the Proximity codec is on and the Wireless VLAN the presentation devices reside on. Also some questions arising on what information is being advertised over the audio signal.
