Class of Service
Each endpoint and each trunk group that is subject to toll restriction is assigned a toll restric-
tion class of service (COS) that restricts dialing patterns on outside calls.
COS is programmed individually for endpoints, voice processing system applications, and
trunk groups. Separate COS designations are available for day and night modes. An endpoint
or trunk group can be completely unrestricted or can have a combination of COSs.
System Speed Dial numbers can be programmed to bypass COS restrictions on a system-wide
basis. If the option is not enabled, all System Speed Dial numbers are subject to toll restriction.
Because a condition may exist where a critical or life-threatening situation needs to be
reported, using the Emergency Call feature code will override all toll restrictions and trunk
access programming.
Note that if the trunk group is not subject to toll restriction, neither the trunk group nor end-
point COS is checked, unless the call is placed using ARS. ARS calls are subject to endpoint
toll restriction only.
The default US and European values for COS appear in the following tables.
Table 22.
Class of Service Default US Values
COS Name Restriction
01 ARS Only This is an endpoint class of service only. It is not used for trunk
groups. Also, the Automatic Route Selection (ARS) feature, which
is standard on the Inter-Tel 5000 platform, is required. Calls can
only be placed using the ARS feature. The user will hear reorder
tones when attempting to place a call using any other method. A
restricted user can still select individual trunks if the trunks are
designated as “exempt from ARS Only,” as described on
page 142, or if they were transferred, were placed on hold, or are
recalling or ringing. Trunk restriction determines which trunks in
the ARS route group can be selected by the endpoint or applica-
tion.
02 Deny Area/
Office
This restriction is divided into eight user groups to allow the use
of varying area/office code restriction tables. This is useful for
reducing restrictions for some of the endpoints, applications, or
trunk groups while increasing restrictions for others. Each end-
point, application, and trunk group is assigned a day mode and a
night mode user group in DB Programming. Within each user
group, area codes can be designated as restricted, allowed, or
extended. Restricting an area code prevents users from placing
calls to that area code. Allowing an area code allows all office
codes within that area code. Designating an area code as
extended allows the programmer to determine which office codes
(up to 800) are allowed or restricted within that area code.
03 Deny
Operator
Calls to operator numbers are restricted.
04 Deny Toll
Access
Calls to numbers containing a toll string (defaults to 1) are
restricted.
05 Deny
International
Calls to international numbers are restricted.
06 Deny Equal
Access
Calls that begin with equal access digits (10XXX or 101XXXX)
are restricted.
