Call security and remote access

System restrictions are required to ensure that your system is used appropriately and not

vulnerable to unauthorized use.

Call security includes:

• restriction filters, which limit outbound call access

• remote access packages, which limit system call feature access for users calling in over the

Private or Public network

• Class of Service codes, which require remote system users to enter a password before they can

access the system. CoS passwords also can have restriction filters applied.

These topics are discussed under the following sections:

• “Defining restriction filters” on page 447

• “Remote call-in programming” on page 451

— “Creating Direct Inward System Access (DISA)” on page 451

— “Defining remote access packages” on page 454

— “Defining CoS passwords” on page 454

Call security works in conjunction with your dialing plan. Refer to “Dialing plans” on page 253.

Defining restriction filters

Restriction filters allow you to restrict the numbers that can be dialed on any external line within

BCM. Up to 100 restriction filters can be created for the system.

To restrict dialing within the system, you can apply restriction filters to:

• outgoing external lines (as line restrictions)

• telephones (as set restrictions)

• external lines on specific telephones (as line/set restrictions)

Restriction filters can also be specified in Restrictions service for times when the system is

operating according to a schedule. Dialed digits must pass both the line restrictions and the set

restrictions. The line per set (line/set) restriction overrides the line restriction and set restriction.

Notes about restriction filters

A restriction filter is a group of restrictions and overrides that specify the external numbers or

feature codes that cannot be dialed from a telephone or on a line. The restriction filters setting

allows you to assign restrictions in one step as a single package of dialing sequences that are not

permitted.
