RE: Firmware upgrade error on T23G

Hi Sir, how was your weekend?

This is Evan from Yealink Support Team, nice to know you here.

The firmware you are using is a special firmware, and it isn't allowed to upgrade the firmware to other FWs(not 44.xx.161.xx) directly, it needs a bridge firmware.

May I know who is your phone provider? Could you please ask them for help? If you can't get the help from your phone provder, please let me know why and send your MAC address of this phone to my private email, evan@yealink.com, then I will let my Spain distributor to help.

Best Regards,
Evan You
