Here is a post on setting up the Crestron Flex System for Microsoft Teams. There are a few setup requirements to pair either the Mercury (tabletop speakerphone) or the TWS-1060 touch panel to the UC Engine.
For official documentation, you can find this all here on the Crestron site.
Crestron Flex Mercury Setup
If you powered up the Mercury and did not select the Teams Video mode, you would have booted it into Generic Mercury mode which means it will be showing a different screen and not the Teams interface. To switch the Mercury back into Teams mode, just follow these steps.
Press and hold the Help button for 10 seconds and you will get a screen showing the IP Address details that have been obtained from your DHCP Server.
Once you have the IP Address, open a browser window and input the address and browse to web server of the Mercury
Now login to the webserver
Now once logged into the Mercury, browse on the left-hand menu to Device > Applications
Now change the mode to Teams Video and click on Save Changes on the right-hand side. The system will now reboot into Teams Video mode.
Find the IP Address of the Crestron Flex UC Engine
So this step is just about getting the IP address what has been assigned to the UC Engine or you can assign a static address to the device.
Step Eleven – Sign Out
Crestron Flex Touch Panel Config
Step One – Config via Mercury or Touch Panel
Step Two – Config via the Web Browser
Step Three – Done
I did a post recently on how to expand the use of say the Creston Flex MTR solutions which can be seen here.
