Use this screen to set up a list of phone numbers that are not allowed to call into
the X2002.
You can also use the letters X , Z and N to represent numbers you want to block.
The letter “ X ” represents any digit from 0-9, Z any digit from 1-9 and N any digit
from 2-9. For example, enter 023XXXXXX to block any 9 digit number that starts
with 023 from calling the extensions configured on the X2002.
