Mitel NuPoint Messenger Technical Documentation - Release 7.0
Interaction between mailboxes is limited by the GCOS and FCOS that are assigned to them. If,
for example, an FCOS allows a user to make confidential messages (feature bit 023), other users
within the same GCOS must be able to receive messages from other users (feature bit 040), and
to play messages (050). Otherwise, the make confidential message feature is useless.

Configuration Requirements

You must assign a GCOS to every mailbox in the system. A GCOS Worksheet (Figure 8-6) helps
you organize the information you need for assigning GCOSs to mailboxes. Fill in the fields on
this worksheet as described in the following paragraphs.

Numbering a GCOS

Put the number of the default GCOS, the number of an existing GCOS that you are modifying, or
the number of a new GCOS that you are defining in the “GCOS to modify” field. If the GCOS is
bitmapped, enter 1 through 64; if the GCOS is an affinity group, enter 65 through 32,000.

Naming a GCOS

Assign a name of your choice to identify the GCOS, up to 15 alphanumeric characters, in the
“GCOS name” field. You only name bitmapped GCOSs (1 through 64).

Assigning Groups

Put the numbers of all groups that comprise a bitmapped GCOS in the “Group numbers” field. An
affinity group GCOS does not contain groups.

Restriction Class of Service
This section covers:
• NPA/NXX screening process
• Default RCOS
• System and specific parameters
• Sequence of NPA/NXX Screening
• Configuration requirements for system-wide parameters
• Configuration requirements for RCOS-specific parameters
• RCOSs and Distribution Lists
• Screening Examples

Overview

Restriction Class of Service (RCOS) is a system software feature that restricts mailbox outdials
to certain area codes, or to certain prefixes within an area code. It can, for example, restrict
outdials to area code 415 only or restrict area code 900 but allow outdials to anywhere else.
During creation or modification of a mailbox, you must specify the RCOS for outdial restricting
capabilities to be operational. If no RCOS is specified in a mailbox’s configuration, outdials are
not screened or restricted.
