Teams device phones missing and offline
I have deployed approximately 60 teams' phones such as Poly CCX400 and Yealink MP54. I noticed only 53 are showing in the portal and 7 are missing but are working on site (one of them is on my desk)....
There was a recent thread on MP54's here
Re: Yealink phones is appearing offline - Microsoft Tech Community
Where it got to was as follows
'I guess you have tried to sign out and sign in again from your phone? I suggest that you remove the device from TAC and register it again, if the issues are not resolved after reboot'
cc'ing in LinusCansby who tested with the MP54 and provided the recommendation
Hope this helps
Best, Chris
