Noise canceling for system sounds of person initiating the call.
System sounds are not being cancelled out for the person initiating the call. When I call my colleague, he hears my system sounds I do not hear his. When he calls me I hear his system sounds and he does not hear mine. They should both be cancelled out like they are in Skype for Business.

Teams needs the noise cancelling and audio devices setting adjustment capability to match what Skype for Business had. It is an incomplete replacement without them.
