Selective Call Acceptance
The INSYS Pocket ISDN can be set to accept only calls from phone numbers that
were previously stored. The following commands allow to create a table with up to
5 or 10 (depending on firmware) numbers.
The INSYS Pocket ISDN ignores each incoming call, which does not comply with
one of the table entries. The INSYS Pocket ISDN compares the number of the caller
with each entry of the list. The comparison starts with the last digit of the number
until an entry complies with. If an entry of the table is configured to asterisk (*), the
INSYS Pocket ISDN accepts every incoming call.
The list is empty as default setting.
Configuration with AT commands
In order to use the selective call acceptance
and define the phone numbers of the
permitted callers in the table acctab, use
the command
Replace <n> with the number of the table
entry here (1 - 5 or 10 (depending on firm-
ware)). <callno> is the transmitted phone
number of the permitted caller. The maxi-
mum length of the phone number is 20 dig-
its. Use the asterisk "*" within the phone
number as wildcard. This is used to replace
one or more digits in the phone number to
permit several similar pone numbers.
AT**acctab<n>=<callno>
Example: only the entered number is
accepted
AT**acctab1=0891234567
Example: The INSYS Pocket ISDN accepts
all numbers starting with 089123
AT**acctab1=089123*
Example: The INSYS Pocket ISDN accepts
all numbers ending with 1234
AT**acctab1=*1234
