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.
C
Conditions
• Before assigning a new COS, make sure the new COS matches the old COS or you may enable
options, 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, PRG 26-01-03 determines if the system should
route over the trunk group settings defined in PRG 21-02 or play an error tone.
• When using ARS Class of Service, with PRG 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, PRG 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 PRG 21-03.
• When using ARS Class of Service, with PRG 26-01-03 set to (1) "Play Warning Tone" or transferred
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 (PRG
20-13-28 = 1).
- An extension can automatically block another extension attempt to change their Class of Service
via Service Code 777 (PRG 20-13-28 = 0).
- The default Service Code for this option is 777 (PRG 11-11-24 = 777).
