Class Of Service (Cos) - 3Com SuperStack 3 NBX Administrator's Manual

Class of Service
(CoS)
Phone Number — An unanswered call goes to the extension number
■
that you specify in this field. Examples: The receptionist's telephone, or
the extension of another hunt group.
Class of Service (CoS) is a set of calling permissions that you assign to
users. Most permissions are subject to the Business Hours parameters:
Open, Closed, Lunch, and Other. For example, you can create a class
where toll calls are allowed during normal business hours (Open), but are
not allowed after business hours (Closed).
Additional considerations:
Emergency calls (such as calls to 911) are not subject to CoS
■
restrictions.
System-wide Speed Dial numbers are not subject to Class of Service
■
restrictions. For example, if you want to enable calling to a specific toll
number to all users without regard to their CoS settings, create a
System Speed Dial for that number.
When you create a new profile, the system assigns the default CoS
■
unless you specify a different one. If you edit the properties of the
default CoS, verify that it contains a minimum set of permissions.
You can enable or disable Offsite Notification at the system level. The
■
system-wide setting takes precedence over the CoS setting.
Service classes control these types of calls:
Intercom
■
External (local, long distance, international, long distance toll-free,
■
and long distance toll)
CO Code (optional telephone company services, such as Call Waiting)
■
Trunk to trunk transfers
■
Off-site Notification
■
To configure Class of Service, select User Configuration > CoS and see the
Help screens for these buttons: Add, Modify, Remove, and View.
