Class of Service (CoS) 133
3 See the online Help for information about how to add, modify, remove,
and view Class of Service.
Note the following 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 telephone 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 Off-site Notification at the system level. The
system-wide setting takes precedence over the CoS setting.
■
A telephone user can override the CoS of a telephone by using feature
code 433. For example, a telephone user with an assigned office
telephone that allows calls to external numbers needs to place a call
to an external number from a conference room telephone with a CoS
that does not allow external calls. The telephone user enters the
feature code into the conference room phone, and the system
prompts for username and password before allowing the call. The
feature code applies to the next call only. After the telephone user
hangs up, the telephone reverts to its assigned CoS.
■
To set an account code as Forced, enable the Force Acct Code check
box for each appropriate Class of Service (click User Configuration >
Class of Service , and then click an extension or Add ).
Verifying account codes is a global configuration setting, while
enforcing account codes is a CoS function. If the CoS setting enforces
the account code for that type of call, a telephone user must enter an
account code before the system routes the call.
■
You can allow telephone users to configure button mappings on their
own devices. Enable User Button Mappings when you add or modify a
group’s CoS settings. If you enable this feature, when the individual
telephone user clicks
Telephone Programming in the NBX NetSet
utility, the system displays the Button Mapping tab, which enables the
telephone user to map functions to telephone buttons. If you do not
enable this feature, the system does not display the Button Mapping
tab.
