If you are using EMG, a template can be used for this.
But if you use WinFiol, a file can be transmitted.
Just make a number of commands like this in a text file:
KSFKC

IR=XXXX,KEY=10,FCN=TNS,DIG=123456;
KSFKC

IR=XXXX,KEY=11,FCN=TNS,DIG=234567;
KSFKC

IR=XXXX,KEY=12,FCN=TNS,DIG=345678;
etc...
If you search and replace XXXX to the extension number in e.g. wordpad or .txt then the file can be transmitted, and the one system phone has all keys programmed.
