[General]
• Call Forwarding applies to a Direct Dialling In (DDI) or
Multiple Subscriber Number (MSN) call.
[To Outside Line]
• A call between two outside parties is established only when
using an ISDN line. A call received through an analogue
outside line must be forwarded through an ISDN line. A call
received through an ISDN line can be forwarded through an
analogue outside line as well as an ISDN line.
• The duration of a call between two outside parties is
determined by the system timer. <[206] Outside-to-Outside
Line Call Duration Time> An alarm tone is generated to both
outside parties 15 seconds before the time-out. The call is
disconnected at the time-out.
[Screened – to Outside Line]

using an ISDN line. A call received through an analogue
outside line must be transferred through an ISDN line. A call
received through an ISDN line can be transferred through an
analogue outside line as well as an ISDN line.
• The duration of a call between two outside parties is
determined by the system timer. <[206] Outside-to-Outside
Line Call Duration Time> Hold Recall is generated to the
extension who transferred the call 50 seconds before the
time-out. The Hold Alarm tone is generated to both outside
parties 15 seconds before the time-out. The call is
disconnected at the time-out unless the extension restores the
conference.
