Class Of Restriction (Cor) - Avaya Communication Manager Administrator's Manual

Call coverage
If you want to ensure that unanswered calls go to office voice mail (rather than the cell phone's voice
mail) make sure the value in the
is set to a lower number than the voice mail coverage setting on the corresponding cell phone.

While stations may have standard Avaya server running Communication Manager voice mail coverage

Although there is no way to indicate a preference for use of a specific system, there is a way to coordinate
the two systems.
It is generally possible to set up the number of "don't answer" rings so that one or the other always
answer first. However, there are coverage options in both the Avaya server running Communication
Manager (busy, active, send-all-calls) and the network (cell phone unavailable, network congested) that
causes a call to immediately go to the respective voice mail. Users should realize that an unanswered call
might result in a voice mail message in either mailbox.

Class of Restriction (COR)

For calls toward a Extension to Cellular/OPS station, COR restrictions are applied normally for a call
terminating to a station. In particular, if the station is mapped, then the office phone's COR applies. Any
restrictions imposed by call filtering are applied after those imposed by the COR. Calling party
restrictions pertaining to trunks (outward, tac-toll, and all-toll) have no affect on the launching of
Extension to Cellular/OPS calls.
DCS
Inter-switch calls on distributed communications system (DCS) trunks are treated as internal calls.
•
When an Extension to Cellular/OPS user has the
Off-PBX Telephone Integration screen set to internal or all, DCS calls are delivered to the cell
phone.
•
When an Extension to Cellular/OPS user has the
DCS calls are not delivered.
Distinctive alerting
Cell phones do not receive distinct rings for different types of calls.
Extension to Cellular enable and disable
Only Extension to Cellular calls (calls extended to a cell phone) can be enabled or disabled. Users can
enable or disable Extension to Cellular calls using either Extension to Cellular enable and disable Feature
Access Codes, or using the enable and disable feature status button.
