RE: T58A - Video calls with Teams
Hello folks,

I ordered the T58A to do video calls in MS Teams, stepped into the trap also and finally got to this thread to read that the phone doesn't support video calls.

Because of a mistake, I accidentally installed the T58 SIP firmware, which shows that the camera is working (as CyB0rg correctly stated in post #2).
But reflashing the correct T58A-Teams firmware failed. The phone was stuck after booting at the bright "Yeahlink" logo. So I logged in via the Web-UI and pulled the syslog for finding the boot error. Finally I got past the boot logo issue by reflashing the T58 SIP firmware, resetting to factory defaults and clearing the internal sd-card and reflashing the T58A-Teams firmware again.

Then I noticed that the camera is not working, so I pulled the syslogs again and digged into it.

While booting it seems that the camera got recognized:

CallPolicy: isVideoCallAllowed() : false lets me suppose, that there is a policy which forbids enabling the video calling.
The PID 3674 is the teams client:
Code:
<134>Feb 10 20:58:33  GUI [1009:1154]: ANDR<6+info  > 2055  3159 I am_proc_start: [0,3674,10021,com.microsoft.skype.teams.ipphone,activity,com.microsoft.skype.team​s.ipphone/com.microsoft.skype.teams.Launcher]

I searched through the Teams admin center for a call policy which may forbid video calling, but did not find anything.
So I suppose that either Microsoft is suppressing video calling due to less performance or there is a config which prevents the Teams app from enabling video.

Maybe someone can try to get the video working on the Teams-edition of the phone, regardless of the bad performance.
I will return my T58A and buy a working phone from another vendor.

P.S.: The Cam50 seems to be just a Sonix Technology SN0001 which is used by Dell in the Inspiron notebooks as well.

A small update:
The camera is working on T58A with SIP firmware, but not with the teams client. It seems that Microsoft or a config setting on the phone is preventing the Teams client from enabling video.
