Forward and Follow Me
Calls received on a personal line (an outside line assigned to a button on the
telephone) are forwarded to outside numbers by using Remote Call Forwarding
only under the following circumstances:
The extension must be assigned as the principal user of the personal line
through system programming. Only one extension can be the principal user
for a given line/trunk.
If the personal line is a loop-start line, it must provide a reliable disconnect
signal. A disconnect signal is the signal sent by the local telephone
company to notify the system that an outside caller has hung up.
Disconnect signaling is considered reliable when a disconnect signal is
sent on every call when the caller hangs up. The line is considered
unreliable when a disconnect signal is not sent on every call. The factory
setting for loop-start lines is Unreliable Disconnect; this setting can be
changed to Reliable Disconnect through system programming. Remote
Call Forwarding cannot be used to forward calls arriving on a line
programmed as unreliable.
Forwarded Call Ringing
A forwarded call rings as shown in
NOTES:
1. Programming a loop-start line as reliable when, in fact, it does
not provide reliable disconnect signaling leaves the line in a
permanent busy condition after a call on that line has been
forwarded to an outside number.
2. In Release 6.0 and later systems, Centrex loop-start lines used
for Centrex Transfer via Remote Call Forwarding do not have to
provide reliable disconnect.
3. T1-emulated loop-start lines are considered unreliable and
should not be used for Remote Call forwarding.
