Using wildcards for call screening
You can make screening more flexible by using the ‘wildcard’
function keys (+ and ?) in the screening number setup
windows. You can insert a plus sign (+) at the start or end of
the number to denote ‘any digit, any series of digits or no
digits’. A question mark (?) anywhere in the number denotes
‘any single digit’. For example:
123 The number must be an exact match—only 123 is
accepted.
123+ Accept any number beginning with 123—e.g. 123,
1234 and 12345.
123? Accept only four-digit numbers beginning with
123. In this example 1234 is accepted, but not
123 or 12345.
For example, if a customer has several CPNs, all identical apart
from the last digit (016285249772, 016285249773, etc.), you
can screen for all of them by using 01628524977?.
