Unable to update Firmware from 66.83.0.55 - Tularis - 09-19-2024 09:11 PM
Hello,
I have 8 T42s Phones and 2 T48s phones, all running firmware 66.83.0.55
We have tried to upgrade the firmware, but the phone just reboots back to the same 66.83.0.55
We have tried to go up a single release, down a single release.
The odd thing is that the yealink website doesn't list 66.83.0.55.
It's as if that firmware never existed...
Any Ideas?
