I can use Polycom Trio 8800 make a call/video to smart phone and it work perfectly fine. But when I start use smart phone to make a call/video call back to Polycom Trio 8800 via "MS Team". It say "the termianl account(Trio 8800) is current unavilable, please leave the message after the tone."
I already update Polycom Trio 8800 's firmware to version 184.108.40.20632 but it still not working!

Hello @Kanate ,
Welcome to the Poly Community.
What type of setup is this?
Calls via the Microsoft 3PIP gateway do not support Video so this may be your issue.

Yeah, lots of moving parts here.
I'm guessing if you're on 5.8.0 still that you're not using Teams mode on the Trio. That means you're in Skype mode. To get calls between Skype users and Teams users to work Mircosoft are doing lots of backend magic, but there are a few settings you have to have right.
Ignore the Trio for a second, pretend you have two PCs. First one has a user signed in to Skype, second one has a user signed in to Teams. Calls from Skype user to Teams user ring on Teams, calls from Teams user to Skype user go to voicemail, which probably means they're trying to ring on Teams, but the first user isn't signed in to Teams.
Go to https://admin.teams.microsoft.com/users and look up both users. In the Teams Upgrade section check the coexistance mode assigned to each user. That controls how the second user's Teams will try to deliver calls to the first user - will it try to connect to them on Skype or on Teams?
If you're using Teams across the board, best bet is to set Coexistance to Teams Only for all users, then upgrade the Trio to the latest firmware, switch the Base Profile to Microsoft Teams, and just use Teams on the Trio too. If your org is still a mix of Skype and Teams then you might need to pick a different option.
Hope that helps at least a little =)
