.
If internal callers use the Leave Word Calling feature when calling another station, they will also
light the MWI lamp on the phone. The person receiving the call does not know whether the lamp
is for message waiting indication or leave word calling indication and will have to check for both
types.
.
In large configurations, there may be delays in message waiting activation and deactivation under
certain circumstances (e.g., broadcast messages). Large configurations can create a high volume of
message waiting commands within a short period of time. People may notice a delay in their lamps
being turned ON or OFF.
Contact your support center if you believe this situation may occur. It is advised that this
possibility be discussed during customer training.
Called Party Identification. Called party identification allows the Octel 200/300 to identify
The source of direct calls (internal extension or external trunk group).
-
The source extension or trunk group, the called extension, and the status of forwarded calls.

With this information, the Octel 200/300 can process the various types of calls appropriately. the Octel
200/300 receives the necessary call information from the System 75 through the digital links of the
ATTIC. The following two sections describe how the System 75 and called party identification work with
the Octel 200/300 call processing features.

System 75 Call Coverage

The System 75 provides several options for call coverage. An individual extension may temporarily have
its calls forwarded to another extension with the Call Forwarding All Calls feature, or groups of
extensions may be assigned a call coverage path for more elaborate coverage.
Call Forwarding All Calls
The System 75 Call Forwarding All Calls feature allows an individual extension to temporarily redirect
its calls to another extension for coverage. This feature can be activated or deactivated at any time from
an extension for which it is configured. The covering extension is specified when the feature is activated.
When Call Forwarding All Calls is active for an individual extension, calls forwarded to the Octel
200/300 will be answered with the prompt "(name) is unavailable."
Call Coverage Path
The System 75 Call Coverage feature provides more selective coverage for one or more extensions with a
designated coverage path. The coverage path determines under what conditions calls are forwarded to
coverage, as well as which extension(s) provide coverage. Coverage paths are defined during the
configuration of the System 75 and may specify the following coverage criteria:
Forward to coverage if extension is active
-
(at least one of the extension's call appearances is in use).
Forward to coverage if extension is busy
-
(all of the extension's call appearances are in use).
Forward to coverage if extension is not answered within a specified number of rings (RNA).
-
Send all calls.
