ok I think I am starting to understand. So if the original text is like this
## Telephone dial plan length (the length of an internal extension number).
## Default is 5. The range is 3 through 10, inclusive.
## For example, if your extension is 12345, your dial plan
## length is 5.
## example:
## SET PHNDPLENGTH 5
And i want to change it 2 4 all I need to do is
## Telephone dial plan length (the length of an internal extension number).
## Default is 5. The range is 3 through 10, inclusive.
## For example, if your extension is 12345, your dial plan
## length is 5.
## example:
SET PHNDPLENGTH 4
And do that to all the changes I need to do.
What if I made no changes to the txt file would I have problems?
