I'm looking for advice on improving the sign-in process for about 30 Teams phones in a shared working environment. We migrated to Teams phones last year for over 500 offices, and while most setups are working fine, one particular business unit is experiencing issues due to their unique operations model.
These users work in a very small space where they share a desk with a government-owned PC. Because of this setup, they cannot use their company laptops to answer calls, so we provided them with C455HD phones. However, these users don't have assigned desks and they switch phones daily.
Initially, signing in using their own usernames and passwords via Microsoft's authentication broker worked, but they soon hit Intune's device limits (20 devices), which prevents them from signing in to any phone. I've cleared the devices in their Intune profiles, but that's not a long-term solution.
I tried the hotdesking feature by creating a base account for these phones, but the user experience was poor — they had to enter long UPNs and passwords directly on the touchscreen, which is cumbersome given the character count of our domain name.
Is there a way to manage the registered devices in Intune or adjust Teams Policies for a better login experience?

One option to consider is deploying higher-end headsets for the users, which could make their call experience much better. You could also think about using device accounts that are assigned to each phone, which might help manage the sign-ins more effectively.

Unfortunately, the current setup doesn’t allow us to use the Teams client on those government-owned PCs, and we can't fit the computers on the desks. As for assigning numbers to device accounts, this isn't feasible since those numbers need to stay with the users for both government and client work.
