How to reduce echo during a conference on Wizyconf Station

Problem

Echo cancellation is not working during a conference on Wizyconf Station.

Solution

Here are some recommendations to reduce echo during a conference: 

1. Use high-quality speakers with clear sound. Any noises or hoarseness can cause echoes
2. Do not set speakers volume level too high
3. Decrease the microphone gain level in Wizyconf Station Settings
4. Decrease the amount of ambient noise in a conference room, e.g. close windows
5. Try to decrease the amount of reflecting surfaces in a conference room room, e.g. close window blinds. Bare walls and windows produce a reflecting sound which causes a lot of echoes
