mask determines how the Directory
Number is changed to map to your
extension numbers. Enter one DDI
number and its associated extension
number. Click Add. You can click its
delete icon to remove a DDI number.
Select multiple check boxes and click
the delete button to remove multiple
DDI numbers.
The DDI mask identifies
digits from right to left, so a
DDI mask of 2 applied to the
incoming ISDN number 555-
123456 would identify the
numbers 56.
• Length and Trusted Peer - Define the
length (1~20) of your caller's extension
number and enter the possible caller's
extension(s). The device only forwards
incoming calls calling from the num-
bers you define in this screen. How-
ever, if you can leave these fields
empty, then the device forwards any incoming calls to extensions regardless of where the
call is from.
