T58A Teams - Call Queues Stopped working

[graeme.carstairs]

Same issue here,
Signing out and signing back in then rebooting the phone and the queues wok properly, then wait 24 hrs or so and the device answers a queue call on hold and you have to take it off hold to speak.
after a few days the device stops ringing for any incoming calls though you can make calls with it, and it shows as offline in teams admin.

These devices are not suitable for a production environment.
