Yealink T42G boot.log

Hi,

I have a YealinkT42G with the last FW - T42-29.80.0.70.rom. I get a file in my tftpserver that is MAC-boot.log and i don want to get it by default, i added in the provisioning file this lines:

syslog.mode = 0
syslog.log_level = 0

And I still get the file.

Is there any way to disable this log?

Thank you.
