Line Text Label Use this field only if you do not want the directory
number to show on the line appearance. Enter text that
identifies this directory number for a line/phone
combination.
Suggested entries include boss’s name, department’s
name, or other appropriate information to identify
multiple directory numbers to secretary/assistant who
monitors multiple directory numbers.
Setting applies only to the current device unless you
check the check box at right and click the Propagate
selected button. (The check box at right displays only if
other devices share this directory number.)
External Phone
Number Mask Indicate phone number (or mask) that is used to send
Caller ID information when a call is placed from this
line.
You can enter a maximum of 30 number and “X”
characters. The Xs represent the directory number and
must appear at the end of the pattern. For example, if you
specify a mask of 972813XXXX, an external call from
extension 1234 displays a caller ID number of
9728131234.
Setting applies only to the current device unless you
check the check box at right and click the Propagate
selected button. (The check box at right displays only if
other devices share this directory number.)
