T46-28.81.0.XX Firmware Bug EXP40

[Lucia_Yealink]

Hi Sir,

About your problem, please share me more information below:
1.Do you mean you use the same configuration with the .20 and .130 version, but the .130 can work normally，right？
2. How many BLF keys you configure?
3. After you upgrade the firmware to the .20, how many BLF LEDs will light up? Or none of them will light up?
4. Please kindly provide the level 6 syslog, config.bin and pace trace when you reproduce the issue, both use the .20 and .130 version, so that we can make a comparison.

About how to get the three files, please refer to the FAQ below:

Best Regards,
