Disabling "Echo Cancellation" on T series phone with Teams?
How do you tweak / disable the "Echo Cancellation" settings on a T5X phone with Teams firmware?

this issue I am having here is occurring on 30+ Yealink phones running Teams. When on speakerphone the callee will hear a background noise that gets louder and louder over time that sounds like a swarm of bees. Hitting mute will stop however will return later in the call.

Only happens on speakerphone.

Cannot find any info on how to disable any of these Comfort Noise Generation features on Teams versions.

It is not the network as non Yealink phones do not have this issue.

Opened a case with Yealink but not getting much help.

Anyone running Teams on Yealink and seeing a similar issue?

Any luck on finding a fix for this? We're experiencing the same problem.

No. Yealink support said they cannot recreate the problem in their labs but we can make it happen any time on any call from any phone using speaker phone.

We have just reverted all phones to Skype for Business to resolve the problem.

If you want to open a ticket with them you can reference my ticket which is Ticket ID: 82130 as they may take this more seriously if they know it has been reported at another location.

Let me know what they say.

My ticket with them is still open and has been escalated about as high as it can go. We're doing testing and trying to narrow everything down. I was able to send them some recordings of the god awful feedback sound so hopefully that will help narrow things down.

If your ticket is still open are if you are still having issues with these phone my ticket number is 84346 if you want to try and reference it and get more people looking into it.

RE: Disabling "Echo Cancellation" on T series phone with Teams?
Yes - THIS!

I posted in another thread regarding the T55 reliability - my CEO says the Yealink phones we just put in are JUNK and wants the removed/replaced. I wish I had pushed for just headsets vs handsets now for our users. Tough audience I have now in all our meetings and Teams is ALWAYS the talking point.

Hope someone can resolve - also all our phones are on the latest firmware.

It is a shame as our CP960 conference phone has flawless audio and blew people away. The T55's not so much.

I have added a ticket too and asked them to reference yours so I hope they can see it is more than a rare occurrence....it's an every day occurence!
