2 Call-Handling Scenarios
Network Configuration Scenarios
Intersystem Calling
This topic illustrates how different types of calls are made and received in
Scenario 1, using the extension numbers and extension equipment types shown
in Figure
how they are displayed at different recipients' extensions within the network. As
you review this information, notice the following features:
Because the private tandem trunks are PRI, the systems display calling
name, calling extension number, or both for arriving non-local dial plan
calls. The display varies according to the display preference programming
for the extension as well as the type of equipment. Contrast this display
with those in Scenario 2,
Wherever a person is in the network, he or she dials another network user
the same way.
Transferred calls within the network display in the same way as direct calls
between extensions. The originating extension information is shown, with
no indication that the call is a transfer.
Both outside callers and callers within the network hear Music On Hold
when their calls are transferred to a non-local extension.
PassageWay client screen displays vary depending upon the PassageWay
implementation. Therefore, the table shows the information that the system
can send to the CTI-linked application; if an MLX-20L
a display telephone receiving the call, the display would appear as shown
in the table.
The last call example shows how Remote Call Forwarding can be used in
combination with Caller ID on a loop-start PSTN line connected to an 800 LS-ID
line/trunk module. The factory setting for Remote Call Forwarding is to prohibit it
for all extensions, so the System B manager must program the original receiving
extension to allow use of the feature. Remote Call Forwarding is turned on by
specifying a tandem PRI trunk and the number of a System A extension. When
the call is received on a System A MLX display telephone, the user sees the
Caller ID information. Had the call been sent over a tandem tie trunk, the calling
party information would not be preserved.
