Look at README.variables! It says:

,----
| The format for removing characters from a variable can be expressed as:
| 
|         ${variable_name[:offset[:length]]}
| 
| If you want to remove the first N characters from the string assigned
| to a variable, simply append a colon and the number of characters to
| remove from the beginning of the string to the variable name.
| 
|         ;Remove the first character of extension, save in "number" variable
|         exten => _9X.,1,Set(number=${EXTEN:1})
