Uploading Skype Firmware on T46 running 28.83.0.55
Hi,

I have 2-3 phones I would like to use for Skype for Business, but am running into issues when trying to install the firmware.

The phones are currently running firmware version 28.83.0.55 which is a custom 3CX firmware version. From what I've read so far, it doesn't look like these phones can be downgraded.

Would anyone have a way to downgrade/upgrade this firmware version so that I can install the Skype firmware?

Thanks.

Dear Customer,


There is a problem with the firmware xx.83.0.55, you should upgrade the phone to xx.83.0.199 first then you can upgrade it any firmware.

Get the 28.83.0.199 firmware from the following link.
