Within the “Audio Device” settings in the Skype for Business Options, the user can change the audio device as well as the volume in for the Speaker and Ringer.



When using RTOP, the result of changing the speaker and ringer volume differs from when RTOP is not in use. The following is the expected behavior:

1. The Speaker volume overrides the Ringer volume. Therefore, if the Ringer and Speaker volumes are set to different levels, the Ringer will continue to use the volume level set for the Speaker.
2. When using a Windows client, if the Speaker volume is changed and the play button is clicked, the volume level is applied immediately.
3. When using a Linux client, if the Speaker volume is changed and the play button is clicked, due to current technical limitations, the volume level is not immediately applied. Instead, the new volume level is applied when an incoming call is answered or when an outgoing call is made.
