Teams standard vs Pro licensing on touch screens
TLDR; Do touch panels on the wall outside of rooms need to use a teams license, or should they just attach using the Crestron Entra app to read the room schedule?
I need a sanity check here.
New building, about 14 conference, huddle and other rooms. General contractor went with a sub to install the Crestron equipment, which is good because I wasn't up to speed with the Teams rooms until now.
In our older buildings, I have touch panels at the door in Crestron Default app mode, attached to the Crestron App in Entra to display the status of the room. The rooms have dedicated PCs or dongles on Air Media devices. Works fine.
In the new building, the vendor has chosen Flex systems for the medium and large conference rooms. Tss1070 or Tss770 room scheduling touch screens outside of the conference and relaxation rooms (and a few more rooms without equipment).
The IT department created the resources in Entra. The vendor was unable to connect the touch screens to Entra. I had to come in to troubleshoot to find that they didn't update the firmware as required to connect to Intune AOSP. One problem averted. We were able to connect one touch screen from conference room 3c to Microsoft 365 (using a Pro license).
On to device #2 (room without equipment), we get the error "Your current license isn't supported" using a standard Teams license. Upgrading to Pro solved the problem. That just adds significant monthly cost.
So, my question: Should the panels outside of the conference room need to be configured as a Teams Room or should the Flex device attached to the monitor and camera have the teams license and the touch panels use the default Crestron Application mode to read/write the M365 resource calendar? From my understanding, the Flex device needs to join the meetings and share equipment, not the device in the hall. Can I save 2/3 of my costs by only assigning Pro licenses to the Flex equipment?
