I can hear background noise when I run a large conference. How can I reduce this?

All participants can help to reduce the background noise on a call by muting their own line when they are not speaking. This can be achieved by pressing the appropriate keypad control on your telephone.

The Host of a Kidatu conferencing call (except Kidatu Freedom) also has control over all the incoming lines, and can mute the entire conference except themselves. This allows the Host to speak to the entire conference without interruption, but also reduces the background noise.
