5.9. Specify Class of Service (COS) and Class Of Restriction (COR)

This section describes the steps for administering the COS and COR, which affects what calling

features and feature options are permitted for defined groups of telephone users.

Step Description

Use the change cos-group n command, where n is a class of service group number, to set

the appropriate service permissions to support the corresponding features (shown in

outlined in red). For the sample configuration, COS group 1 was used. On Page 2, set

the value of VIP Caller to “y” only if all calls made by telephones with this COS should

be priority calls. Note that priority can be requested on a call-by-call basis by using the

Priority Call FNE (see Section 5.8). Priority call indication (e.g., distinctive ring and

display of “Priority”) is only supported on Avaya Digital and 9600 Series IP telephones

(H.323 and SIP).
