Plantronics + Polycom.
Now together as
Phone Model Trio 8800Part Number 3111-65290-001 Rev:AUC Software Version 184.108.40.20621
We are using O365 with Skype for Business E1 & E3 licenses.
I have created an online account (*onmicrosoft.com) for our polycom device. I'm also able to log in and attend planned meetings or open a quick meeting.
Unfortunately, I'm not able to add any other attendant or directly call someone. (busy signal)
When I'm logging in via Skype for Business, it works.
Thanks for you help.
