1.3.1.2 Call Forwarding (FWD)

Description

Extension users can forward their calls to preset destinations. There are 4 Call Forwarding (FWD) modes, described below.

Mode Description All Calls  All calls are forwarded to another extension. Busy/No Answer  Calls are forwarded when the extension user's line is busy, or when the user does not answer within a preprogrammed time period ( Call Forwarding Start Time [202]). To Outside (CO) Line  All calls are forwarded to an outside party, provided this feature is enabled for each extension through system programming ( Call Forwarding to CO Line [607]). Follow Me  When an extension user fails to set this feature before leaving his or her desk, this feature can be set from the destination extension.

[Available Destinations]

Destination Availability Extension (proprietary telephone [PT]/single line telephone [SLT]) – Automatic Line Access no. + Phone no. Only available when FWD to Outside (CO) Line is enabled for the extension through system programming ( Call Forwarding to CO Line [607]). Outside (CO) Line Group Access no. + Outside (CO) Line Group no. + Phone no. Only available when FWD to Outside (CO) Line is enabled for the extension through system programming ( Call Forwarding to CO Line [607]). Voice Processing System (VPS) – Built-in Voice Message (BV) feature no. Only available when the BV feature is enabled for the extension through system programming ( BV for Extension [622]).

Conditions

[General]
•	This feature does not apply to calls from Hold Recall and Camp-on Recall.
•	The types of calls that are forwarded by this feature are:
	Call Type Outside (CO) line calls Normal except FWD to Outside (CO) Line, Direct In Line (DIL), Direct Inward System Access (DISA) Intercom calls Extension, Transfer
•	Uniform Call Distribution (UCD) When searching for an available extension within a UCD group, any extension that has set FWD will be skipped. However, if the last extension that can receive a call has set FWD, the call will be forwarded to that extension's call forwarding destination. The last member of a UCD group cannot log out.
•	When a call is forwarded, the corresponding message waiting indication is not forwarded. The MESSAGE button light or Message/Ringer Lamp turns on only at the originally called extension ( 1.17.1 Message Waiting).
•	It is programmable whether the calls received on outside (CO) lines programmed as "Normal" ( CO Line Mode—Day/Night/Lunch [414-416]) are forwarded for each extension or not ( Call Forwarding Selection [963]). If FWD is enabled for an extension whose FWD destination is a VPS or Telephone Answering Machine (TAM) and the extension has been assigned to ring with other extensions, the VPS or TAM may answer the call before other extensions can answer it. To prevent this, disable FWD.
•	A call can only be automatically forwarded one time. In the example below, extension A's calls are being forwarded to extension B. If extension B tries to set FWD to extension C, the extension B user hears a reorder tone and the setting is denied. If extension B has already set FWD to extension C, and extension A tries to set FWD to extension B, the setting is also denied.
•	The destination of an extension's forwarded calls can call or transfer calls to the original extension.

[Busy/No Answer]
•	No Answer Time The length of time before calls are forwarded is programmable for each extension ( Call Forwarding Start Time [202]).

[To Outside (CO) Line]
•	FWD to Outside (CO) Line System programming determines the extensions that can forward all intercom calls and certain outside (CO) line calls to an outside party ( Call Forwarding to CO Line [607]). These outside (CO) line calls must arrive on outside (CO) lines whose programming ( CO Line Mode—Day/Night/Lunch [414-416]) is one of the following:
	a) DIL b) DISA (only when the call is directly sent to an extension, not intercepted) c) UCD (when only one member belongs to the group)
•	Outside (CO) Line Call Duration If a call between 2 outside parties is established, the call duration will be restricted by a system timer ( CO-to-CO Line Call Duration [205]). Both parties will hear a warning tone 15 seconds before the timer expires. When the timer expires, the call is disconnected ( 1.10.8 Outside (CO) Line Call Limitation).
•	If a CPC (Calling Party Control) signal or reverse signal is received from an outside (CO) line, the corresponding call between 2 outside parties will be disconnected.

•	DND Override An extension in DND mode can be called by extensions that are allowed to override DND through system programming ( DND Override [609]).

•	Calls from outside (CO) lines programmed as "Normal" or "DIL" ( CO Line Mode—Day/Night/Lunch [414-416]) can be received at a user's extension, but the telephone will not ring. The corresponding CO button will flash when an outside (CO) line call is received, and the user can answer the call by pressing this button.
