Firmware update for EXP40

[Argenture]

Good day
We have two T46S phones each with a EXP40 connected. With the T46S on the latest firmware (66.84.0.15) I noticed that the one EXP40 will not always show the BLF key as busy. When I logged in on the web interface I saw that the hardware version of both EXP40's are the same (66.16.0.0), but the firmware is different (11.16.0.0 vs 10.16.0.0)
The one giving problems is on v10.16.0.0. Is 11.16.0.0 the latest version and how do I upgrade the firmware of the EXP40?
Kind regards,
Werner

Dear Customer,

This is Baron from Yealink, I will work with you on this case.

1.Could you tell me how many Dsskey have you set?Included on the phone and on the EXP40.
2. Could you please try to replace another T46S to this abnormal EXP40 to avoid the T46S has some wrong configurations?
3.If you configure BLF on phone itself, can it work fine?

Hope that I have make this question clear to you and just let me know if still any question.

Best Regards,
Baron
