Polycom Trio 8500 - Audio Problems

Re: Polycom Trio 8500 - Audio Problems

Hi - I'm having exactly this problem with a RealPresence Trio 8500.


"We a a problem with the speaker voice quality during a call.

If the microphone is muted the voice quality of the integrated speakers is excellent.

But if I activate the microphone the voice from the speakers is interrupted/intermittet and hard to understand..sometimes louder sometimes quieter."

That describes it exactly.

It's also reproducable with the inbuilt Audio Diagnostics tool.

Can you advise me on the what the resolution could be?

They were non-helpful. The claimed that the unit must have been a refurbished unit. I bought from the internet and both units as far as I noticed were new. Both were terrible. I am not doing anything at this point. Wish you luck.

Hello everyone,


I would give the following technical advisory a review, as it sounds like some (not all) replies to this thread are consistent with the behavior of this known issue:


If the issue that you are experiencing is consistent with the known issue mentioned in the technical advisory, the only recourse may be to RMA the unit from remediated stock.
