Hi support

Device Information:

Phone Model Trio 8800
Part Number 3111-65290-001 Rev:A
UC Software Version 5.9.0.11421

 

Environment:

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.

 

Issue:

Unfortunately, I'm not able to add any other attendant or directly call someone. (busy signal)

 

Note:

When I'm logging in via Skype for Business, it works.

 

Thanks for you help.
