But i make a mistake an installed from the 58... to 55.9.0.14

Now i want to update do the 58.58.83.0.15

the update process started but nothing happens after the process finished.
the firmware on the t58 show always 55.9.0.14

Hi,

By default, the phone has a built-in Skype for Business feature license, which allows user to use Yealink phones with Skype for Business features directly.
Any Open SIP build upgrades to Skype for Business build will be required to apply and import the license.
Any Skype for Business will not be allowed to downgrade to the Open SIP from this release (55.9.0.14). If Skype for Business phones are under temporary license (for demo testing purpose) and want to get back to Open SIP, please contact Yealink support team for technical support for a unlock license.

Hope this will help.

Kind regards,
Frank.

I am not an employee of Yealink.

Please do not send unsolicited PM messages. I will not answer them.
