Hello @pdel800 ,
Welcome to the HP Poly community.
From our UC FAQ:
Nov 04, 2021 Question: Are Poly Trio 8800 and 8500 supported to be used with Microsoft Teams?
Resolution: As explained >here< the Trio 8800 and 8500 are no longer supported as a Microsoft Teams device since 31/10/2021.
The Microsoft Teams App included in any current Poly UC Software build for Trio 8800 and 8500 is 1449/1.0.94.2020051601
Basically the Poly trio 8500 and Trio 8800 are no longer supported to be used with Microsoft Teams.
As you did not post your current software the menu option may just not be available depending where you are looking for it.
Our General VoIP FAQ has this:
Aug 27, 2021 Question: Why do I not see the different Base Profile modes offered when factory resetting /OOB / Out Of Box wizard a Poly device?
Resolution: Please check => here <=
As the Microsoft Teams application is back from 2020 and cannot be updated even downgrading the Firmware will not help you with this being unsupported by Microsoft.
Best Regards
Steffen Baier
