Class of Service
Description
Class of Service (COS) sets various features and dialing options (called items) for extensions. The
system allows any number of extensions to share the same Class of Service. An extension can have a
different Class of Service for each of the Night Service modes. This lets you program a different set of
dialing options for daytime operation, nighttime operation and even during lunch breaks. An extension
Class of Service can be changed in system programming or via a Service Code (normally
777
). There
are 15 available Classes of Service.
Conditions
•
Before assigning a new COS, make sure the new COS matches the old COS or you may enable op-
tions, which the extension should not have or remove options, which it should have.
•
An extension can have a different Class of Service for each Service mode. At default, the Mode
names are assigned as follows:
- Mode 1 = No setting
- Mode 2 = Night
- Mode 3 = Midnight
- Mode 4 = Rest
- Mode 5 = Day2
- Mode 6 = Night2
- Mode 7 = Midnight2
- Mode 8 = Rest2
•
If a user dials a number not programmed in ARS, Program 26-01-03 determines if the system should
route over the trunk group settings defined in Program 21-02 or play an error tone.
•
When using ARS Class of Service, with Program 26-01-03 set to (1) "Play Warning Tone", Any trunk
pointed or transferred to a virtual that is Call Forward Off-Premise will not complete. For a virtual to
Call Forward Off-Premise, Program 26-01-03 must be set to "Route to trunk group" and the call will
follow the trunk group settings of the trunk, assigned in Program 21-03.
•
When using ARS Class of Service, with Program 26-01-03 set to (1) "Play Warning Tone" or trans-
ferred to a virtual that is Call Forward Off-Premise will always follow ARS Class 1 routing properties.
Default Settings
•
All extensions have Class of Service 1 in all Night Service modes.
If changing Class of Service via Service Code:
- An extension can use Service Code
777
to change another extension Class of Service (Program 20-13-28 =
1).
- An extension can automatically block another extension attempt to change their Class of Service via Service
Code
777
(Program 20-13-28 = 0).
- The default Service Code for this option is
777
(Program 11-11-24 =
777
).
