Function
The list of phone numbers may also contain wildcards "'*". This
allows the activation of entire blocks of phone numbers. The
wild card character ("*") replaces exactly 1 character of the
phone number
Our example will activate all phone numbers that start
with 94158692** and have 2 more digits (e.g.: an
extension).
The phone numbers can be deleted individually in two different
ways.
Display the last phone number whose call was rejected. This
phone number is not saved in the power fail-safe memory of
the modem, i.e. after a restart of the modem the display will be
empty.
14
The phone number may not contain separators
such as brackets or space characters.
Delete the entered phone number e.g.: Delete the
number stored at the storage location 5
Overwrite the storage location with a new phone
number. e.g.: Storage location 5 with phone
number 456
