Teams Mobile Calls to Teams Desktop App Drop

[NickTT]

We noticed a strange issue. If someone calls a user in Teams.. from the Mobile App and click answer... the call will drop immediately. However, if Teams is running on a non VDI machine, it works fine. Doesn't matter if the caller is external or internal to the company.

We are running Horizon 2306.

My Teams VDI version is 1.6.00.29964. Though we are seeing this same situation with other versions of Teams.

Looking at the Teams call logs I am getting "Response code: 410"

The fix is to uninstall the Mobile App and Reinstall it. Then it starts working fine. Not sure what that is about but it fixed the issue for the few users having the issue on our side.
