W90DM annoying hum , crackles during call - reed - 06-17-2022 05:20 PM

Hello,

Please forgive me if it is in wrong place, but i can't see - dedicated subforum for W90DM.
I got a problem with Yealink W90DM 130.85.0.15 (3 bases) and over 50 W53H handset.
Sometimes during a call you can hear very loud and annoying sound (Can't attached file to this post, and also provide link to this file.). Before playing make sure your headphones or speakers are adjusted to low volume. Codec used when establishing call is PCMU / PCMA. Network connection OK, without drops.

Do you have any idea what it might be? How I can fix it.

It could be some external interference, what kind of enviroment is it? This kind of behaviour can also be triggered by a reflective enviroment.
