Table 10: Default U.S. Class of Service ValuesCOS Name Restriction
01 ARS Only This is a phone class of service only. It is not used for trunk groups. Also, the
Automatic Route Selection (ARS) feature, which is standard on the 5000 CP, is
required.
Calls can only be placed using the ARS feature. The user hears 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, 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 phone or
application.
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 phones,
applications, or trunk groups while increasing restrictions for others.
Each phone, 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.
07 Deny Local
Calls Calls to local numbers are restricted.
08 Denied
Numbers Calls to programmed denied numbers (defaults to 1900NXXXXXX+ and 976XXXX+)
are restricted.
09 Allowed
Numbers Calls to programmed allowed numbers (defaults to 1800NXXXXXX+) are allowed,
even if the number also matches a dial pattern in a restricted class of service that is
assigned to the phone, application, or trunk group being used.
COS designations 01 to 09 have default values. COS designations (10 to 16) do not have default values and are
blank. All COS values are programmable. Each may be specified as an allowed or denied class of service, dialing
patterns can be programmed for each, and each can be assigned to phones and trunk groups as needed.
