6.7.1 The Call Blacklist Screen
Use this screen to set up a list of phone numbers that are not allowed to call into
the X6004.
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 X6004.
Furthermore, you can use the period (.) as a wildcard, to block any numbers that
begin with a pattern of digits you specify. For example, enter 555. to block any
numbers starting with the string 555 from calling the extensions configured on
the X6004.
