With Automatic Callback, the call is automatically queued;
however, if the user tries to add the queued call to the
conference, the system returns a busy tone. With Selective
Callback, the system also returns a busy tone. The user must
press the Drop button and the line button used for the call to
drop the busy tone from the conference.
The sender and all Coverage receivers must be busy before a
call to a sender can be queued. The call is sent to Coverage
before it is put in the Callback queue. Once a call is in the
Callback queue, it is not sent to Coverage again. The Callback
call indicating that a busy extension or pool is available is not
eligible for Individual or Group Coverage.
When a call is queued by Automatic Callback on multiline
telephones or by Selective Callback on analog multiline
telephones, the display shows a feedback message. When an
MLX telephone user activates Selective Callback, the display
prompts the user to enter the telephone number. When the
queued call rings the user’s telephone, the display indicates
that it is a returning Callback call.
Calls to extensions that are using Do Not Disturb are not eligible
for Callback queuing. If the Callback originator is using Do Not
Disturb, the system overrides the feature and the telephone
rings when the busy extension or trunk is available.
In the Hotel mode, an extension in Extension Status 1 or 2
cannot use Callback to request busy pools.
An account code must be entered before Callback is activated.
If not, the user hears a busy tone.
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.
When a user with Automatic Callback activated selects a pool
on which to forward calls to an outside number and all trunks in
the pool are busy, the caller hears queuing tone when the call is
queued for the busy pool. When the pool is available, the caller
hears the dequeuing tone and the call is forwarded.
When a user with Automatic Callback deactivated selects a
pool on which to forward calls to an outside number and all
trunks in the pool are busy, the caller hears a busy signal to
indicate all trunks in the pool are busy. The user can activate
Selective Callback and queue the call for the forwarding
telephone and not the busy pool. Outside callers cannot use
Callback when the forwarding telephone is busy.
