You can design up to eight lists with a maximum of 10 numbers. Each number can
have up to 11 digits, for example, a leading 1 (if a toll-call prefix is required for
dialing) followed by the area code and telephone number. Star codes (such as
*67) may also be included in the list to block users from accessing special
services offered by the Central Office. Once you have designed the lists, decide
which telephones to restrict. You can assign up to eight lists for each telephone.
Disallowed List 7 is the system default list and includes the numbers most
frequently associated with fraud. The table below lists the factory set entries for
Disallowed List 7.
Table 4–2. Disallowed List 7 Factory Set Entries
NOTES:
1. Users cannot dial a number on an Allowed List if it matches a number on
a Disallowed List assigned to the telephone.
2. For a private network environment, see the
Network Reference
for
planning Disallowed Lists needed to restrict calls across the private
network.
Planning Form Instructions 4
On Form 6f:
1. Write the name of the list in the space next to the list number.
2. Write the disallowed area codes, exchanges, and/or star codes in the
spaces provided (a maximum of 10 entries for each list). Use the wild card
character (“p”) to restrict an exchange from being dialed in any area code.
For example, to prevent users from directly dialing the 976 exchange in any
area code, write
1 p p p 9 7 6.
NOTE:
On Form 6f (page 3), Disallowed List 7 contains factory set entries
(as shown in Table 4–2
above) and is the factory set disallowed list.
To change the entries in this list, cross out the entry and write the
new values in the space provided.
