Instruction manual

Features
■ On an outside call, when the system is using host switch services such
as Centrex, the signal may be sent to the host, depending on the type of
telephone and system operating mode.
— A multiline telephone user can use Recall to access host
features. The user can be connected to another party or can be
listening to outside dial tone, ringback, or a busy signal.
— A single-line telephone user can use Recall to access host
services only if the system is programmed for the Behind Switch
mode of operation,
Recall is used by pressing a fixed or programmed Recall button or dialing the
Recall feature code. The Recall Timer, which specifies the duration of the
switchhook flash, is set through system programming. The duration required by
the host switch is specified by the local telephone company.
The Recall Timer should be reset if multiline telephone users experience either
of the following problems:
■ When the user presses the Recall button on an outside call, nothing
happens. This indicates that the interval is too short and should be
increased to 650 milliseconds or 1 second.
■ In a system operating in Behind Switch mode, when the user presses the
Recall button on an outside call, the call is disconnected. This indicates
that the interval is too long and should be decreased to 350 ms.
Release Differences
Release 1.0 or Release 1.1
Recall can be used on an outside call only if the call has been made or received
on a Personal Line or Pool button. Recall cannot be used on an outside call
made or received on an SA or ICOM button.
Release 2.0 (or Later)
In addition to calls made or received on a Personal Line button or a Pool
button, Recall can be used on an outside call made or received on an SA
(including Shared SA) or ICOM button. This includes the following kinds of
calls:
■ Transferred calls, Group Calling, and forwarded calls received on an SA
or ICOM button.
■ Automatic Route Selection (ARS) calls and calls made using a pool dial-
out code (on SA buttons) or using the Idle Line Access code (on ICOM
buttons).
