Blocking Calls to Area Codes from All Extensions
To add or edit system prohibited area codes:
1. Double-click an index entry in System Prohibited Prefixes list, or
select the index entry and click Edit. This opens a dialog box that
allows you to enter a prefix number.
2. Enter a 1 and the dialing prefix to block (e.g. 900, 976). You can
enter up to 20 digits maximum for each prefix. For example, to
block calls from all extensions to 976 numbers, type 1976.
3. Click Apply.
Setting Toll Call Prefixes
AltiWare uses the Toll Call Prefixes to determine the type of outside call
and imposes restrictions when necessary. For example, if the international
toll call prefix is 011 and a user attempts to make an international call from
an extension without international call privileges, the call will be
terminated as soon as the user dials 011 after the trunk or route access
number. The caller hears an error tone.
The toll prefixes set here should match the dialing plan prefixes for the
country set in the General window (see page 22).You can set the following
toll call prefixes.
• Domestic. The dialing plan for your country or region. For example,
type in a 1 for 1-plus dialing within the U.S. dialing plan (also known
as the North American Numbering Plan).
• International. The prefix used for international calls. For example,
this is 011 for international calls made in the USA.
• Other. Flexible and variable uses such as a string of digits to be
considered non-local.
Blocking All Outgoing Calls
To block all outgoing calls—for example, when testing or modifying the
system—select the Block All Outgoing Calls check box.
