How to fix echo on calls using headset with VVX 400?

I have 1 VVX 400 for my use at home, and when I use a headset, the person I'm speaking to hears an echo of themselves.


I've already turned on "Echo Cancellation" with no luck.


It sounds similar to this issue.

Hello @MrAlex ,


welcome to the Poly Community.


A couple of questions:


  • Is this a day one issue or has this recently changed due to a firmware upgrade?
  • Are this external calls only or internal/external?
  • What type of headset with what connection to the phone?

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
