PSTN Wind Sound ( Canada )

I have an issue with a S100 unit with FXO port ( last firmware ).

When i speak i always hear some kind a wind Sound.

Yeastar told me this problem come the echo cancelling.


``From Yeastar ,  it was caused by incoming signal is too weak and our echo cancellation algorithm is too strong so that involved that wind sound when you talk``

Is there anyone who has a similar problem?


My client is with Bell Canada ( traditional copper line).


Thank you all
