Features
Recall/Timed Flash
Recall is used by pressing a fixed or programmed Recall button (or Flash button
on some single-line telephones) 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 and 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 and Later
In addition to its use on 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, group, and forwarded calls received on SA or ICOM buttons
Automatic Route Selection (ARS) calls and calls made using pool dial-out
codes (on SA buttons) or Idle Line Access codes (on ICOM buttons)
When used after dialing is completed on an outside line/trunk, Recall sends a
timed flash to the host switch, the line/trunk is kept, the user hears a new outside
dial tone, and calling restrictions are reapplied. On an ARS call or a call on a
rotary-dial line/trunk, Recall cannot be used until dialing is completed. On a call
made using the pool dial-out code, Recall can be used during, as well as after,
dialing. Recall can be used only on loop-start lines.
Considerations and Constraints
Recall can be used to send a timed flash to the host switch only on loop-start
lines.
The Recall or Flash button sends a switchhook flash. It is not a "redial" button.
