Class of Service (COS)
What's this?
Class of Service (CoS) defines the permission an extension will have on a PBX. It defines the set features of the
PBX that the extension is to be allowed access to.
Feature requirements vary among users and with time. Certain groups of extension users may have a need for
voice mail, while another group may need the ability to forward calls to a cell phone, and still others may have no
need to make calls outside the office.
Similarly, certain features that are required during working hours may not be required during non-working hours.
ETERNITY NE offers the flexibility to allow or deny extension users access to features of the PBX, on the basis of
their requirement and according to time of the day. For users, access to various features from their extensions is
their Class of Service (Cost).
How it works
Each extension port of the PBX has an associated CoS for the Day and Night, that indicates which features of the
PBX the port is allowed to access during working hours and during non-working hours.
A feature can be allowed or denied to an extension by enabling or disabling it in the CoS of that extension.
The CoS of all extensions may be uniform, or different CoS can be assigned to different extensions, according to
the time of the day. Doing so, each extension can access a different set of features during the Day (working hours)
and at Night (non-working hours).
Basic Features
A set of features including Internal Call, Call Hold, Call Toggle, Call Transfer, Department Call, Operator Access,
Redial, and Call Mute defined as Basic Features and allowed in the CoS of all extensions.
It is not possible to enable or disable selectively any of the features included in "Basic Features".
