Barge-In
Callback
A user with an outward- or toll-restricted telephone cannot forward calls
to an outside number unless the number is on an Allowed List assigned
to the restricted extension. No error tone sounds when a user with a
restricted telephone uses Remote Call Forward. However, when a call
eligible for forwarding is received, the system checks restrictions and
denies the forward if the outside telephone number is not on an Allowed
List assigned to the restricted extension.
An answering device connected to an analog multiline telephone can
answer forwarded calls when Auto Answer All is turned on.
To have ARS select the facility on which to forward calls to an outside
telephone number, enter the ARS code before the telephone number.
The Facility Restriction Level for the call is that of the extension from
which calls are being forwarded.
When a forwarded call is answered at the destination extension,
Barge-In can be used to join the call only by dialing the extension
number for the destination extension (not the number for the originating
extension). Barge-In cannot be used to join a call forwarded to an
outside telephone number.
If a user queues a call and then uses Forward, Remote Call Forward, or
Follow Me, the call does not ring back at the destination extension or
telephone number; the callback call returns only to the forwarding
telephone.
If a forwarding extension is busy when a user calls, the user can queue
the call for callback. Callback is completed when the forwarding
extension is no longer busy. If the forwarding extension and the
forwarded-to extension are available, the call rings at both extensions. If
the forwarded-to extension is not available, the call rings at the
forwarding extension only.
If an inside caller using Automatic Callback calls an extension with
Remote Call Forward and no pools are available, the caller hears
queuing tone. When the extension becomes available, dequeuing tone
is heard and the call is placed to the extension (not the Remote Call
Forwarding number) if the user has stayed on the line. Otherwise, if the
caller has hung up, priority ring is heard as the callback call is
dispensed to the user.
If an inside caller without Automatic Callback on calls an extension with
Remote Call Forward, and no pools are available, the call follows the
extension's coverage path, if any. If there is no coverage, and the inside
caller activates Selective Callback while listening to the busy signal, the
call queues for the extension but not for the Remote Call Forward
number.
