Hello,
we're using a Polycom Trio 8500 confernce phone.
Software-release: 5.7.1.4133
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.
First I though a codec/network-problem or something like this, but the error only appears if the mute-mode of the microphone is disabled.
Has anyone an idea to solve the problem?
Thank you and regards from Germany, Nils

Please get this into support as there is some data we need to check.

We already had the unit replaced, exact same issue with new unit. Is this a common issue that requires replacment? or is this a settings issue.
Seems unlikely that both units would have same defect unless its very common, and it dosent seem to be that common as there arnt many posts on here about it.
Where do i find the MAC address for the unit?
Please dont just respond to the last question only.

Was there a resolution to this? We are experiencing the same issue on multiple Trio 8500 units in our environment. We are currently running firmware 5.7.1.4145 and have tried with noise cancelling enabled and disabled with no luck. Our Trio 8800s work without issue.

Hello @Joe P.,
welcome to the Polycom Community.
Please work with your reseller on an RMA for the affected hardware.
If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.
