T43U_BLF Like Key randomly changes to Line key Type DND

[Balavan]

Hi All

I'm having a problem with a Yealink T43U.it automatically changes the BLF line key to DND Type. this happens at random intervals, even if the phone did no reboot.

This is the normal setting as it should be.

This is the problem- This line key 3 is changing to DND.
When you click this line key it activates DND on the this phone.

I hope this is enough to help solve this problem.

Thank you.
