RE: Can't recover T48G via TFTP
@johnkiniston
Thank you for your replay, but I tried this too.

It happens that I could solve the issue with the help of the yealink support and wanted to share this with everyone in case you have the same problem.

It seems that the internal CA-Certificate of the T48S can cause conflicts with some SIP servers. In that case you have to access the web interface, go to "security", "trusted certificates" and set "Only accept trusted certificates to "disabled".

That's it. Now the phone works flawlessly.
