Recall / Timed Flash
Recall sends a momentary signal called a timed flash or switchhook flash while the telephone is on the hook. A timed flash is used as a control signal, as follows:
- On an inside call, the signal is intercepted by the control unit.
- A multiline telephone user can use Recall to disconnect a call and get a new dial tone without hanging up. The user can be on an active call or listening to ringback or dial tone. When the user is listening to a busy signal, Recall has no effect.
- A single-line telephone user can use Recall to put an active call on hold and to access system features such as Conference and Transfer.
- 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 4400, 4400D, or single-line telephone user can use Recall to access host services only if the system is programmed for Behind Switch mode.

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.

In addition to its use on calls made or received on a Personal Line or 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.
- 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.
