Magix R1.5: Wildcard characters in ARS 6-digit
tables
Release 1.5 of the MERLIN MAGIX system allows one-to-one wildcard character
matching in the area code entry (not the exchange code entry) of 6-digit tables.
This allows ARS to program numbers such as directory assistance
(xxx-555-1212) for multiple area codes with one entry.
****SECURITY ALERT****
Some regions charge for directory assistance. Also, many directory assistance
calls ask you if you want to dial the number for an additional charge. Use FRLs to
restrict the user from making directory assistance calls. Use the Hold button to
enter a wildcard character when you program a 6-digit table. The wildcard
character appears as “p” on a telephone display and on the printed report.
Disallowed lists 3
Use this procedure to establish disallowed lists. These lists are telephone
numbers that cannot be dialed from specified extensions (including unrestricted
extensions). A maximum of eight lists (numbered 0 through 7) with 10 entries
each (numbered 0 through 9) is allowed. Each number can have a maximum of 11
digits, including wildcards. The Pause character (entered by pressing the
Hold
button) is used to designate a wildcard character—for example, to indicate that
calls to a given exchange are restricted in every area code.
****SECURITY ALERT****
Create a disallowed list or use the pre-prepared Disallowed List number 7 to
disallow dialing 0, 11, 10, 1700, 1809, 1900, and 976 or 1(wildcard)976.
Disallowed List number 7 does not include 800 and 1800 and 411 and 1411,
but Avaya recommends that you add them. Assign all voice mail port extensions
to this disallowed list. Avaya recommends assigning Disallowed List number 7.
This is an added layer of security in case outward restriction is inadvertently
removed. (Voice messaging ports are assigned, 3 by default, to Disallowed List
number 7.)
