The manual says that if I have a permanent license, it not allowed to downgrade. But the phone come with a Open SIP firmware and upgraded to Teams and order a permanent license over Yealink Portal.

After flashing on Teams Firmware, I found out over the forum, the video call doesn't work Angry
So I downgraded from the Teams firmware back to the Open SIP firmware and now it hangs on the Yealink Logo with black background.
Beacause I will returned it back.

Hi,

I think the best you can do is open a support ticket @ Yealink and ask if they can help.

Kind regards,
Frank.
