MS Teams IP-Phone shows allways Offline

Question

Dear Community, we face a strange behavior with MS Teams IP-Phones (Model Yealink MP54) and Microsoft Teams Room Standard License. The Device Firmware and MS Teams App is uptodate and the sign-in was successfully. In the Teams Admin Center of Devices, the Device is healthy. But the Device is allways Offline, no Calling for In-/Outbound thru Direct Routing is working. Calendar Access and join to Online Meeting is working as expected. The same IP-Phone Model with a common area phone license is Online and calling is working as expected. If I register a Poly Trio C60 with same Account and same MS Teams App version, the Phone is online. Is this a known Issues and how can we solve this problem.

many thanks for any replay
