T46G - How to "lock" the line keys?

[Yealink_Peter]

Hi tb303,

You'll find the Line Key's description when searched by "linekey" from the Common.cfg File, parameter's format as bellow,
linekey.X.line =1
linekey.X.type =15
linekey.X.value =2 ## 0=Default,1=Float,2=Lock ##

By the way, you can add them to MAC file if you would like to provision via MAC.

Thanks.
Peter
