RE: Change fimware from Enreach / Swyx to 3CX
Hi,

thanks for your reply.
I have a Yealink T48s with the Firmware 66.85.133.10.

But your link helps me! I had to downgrade the Firmware to 66.84.133.12 and then create a license at the Yealink License Center. Then it was possible to Upgrade to the Firmware version 66.86.0.15.
