Noise and Echo

Thanks jitsi team for this wonderful platform. we have setup jitsi on our server. Everything is working fine. But the problem is huge noise and echo. if we compare the same with facebook messenger, google meet or even zoom, there is no noise and echo. But using jitsi generating huge noise, specially if any ceiling fan is running, or a bus is passing by, some noise like a storm is coming and as well as echo. But in same scenario zoom, fb messenger or google meet is working nicely. no disturbance sound. Please note that Audio processing is enabled and as well as noise suppression and echo cancellation is also enabled.
Can you please help on this if there is any other parameter to set to reduce this noise, its very disturbing.

@damencho expecting some help from you. Thanks in advance.
