Calls made to a calling group are not eligible for Callback because
the calls ring into the calling group's queue. Callback can be used,
however, for calls to individual calling group member extensions or
to delay announcement devices. Calling group calls are not sent to a
group member when the member has used Callback for a busy
extension or pool, or if another person used Callback to reach the
member and the callback call is ringing on the member's telephone.
In Release 6.1 and later systems when a call is sent to a calling
group with a non-local member and no tandem trunks are available,
the system automatically provides Callback to queue for an
available trunk.
Callback calls are answered automatically by using Headset Auto
Answer, but a user hears the out-of-queue tone instead of the zip
tone. When both calling and receiving users have headsets with
Headset Auto Answer activated (MLX telephones only), the person
being called hears the zip tone when the callback call is completed;
the callback originator does not hear zip tone or dequeuing tone.
Pressing the Hold button while waiting for a callback call is similar to
hanging up. The green LED next to the line button flashes,
indicating that the button is being used for the queued call.
Callback is not intended for HotLine extensions (Release 5.0 and
later systems). Automatic Callback, however, can be used, if
programmed, for inside and ARS (Hybrid/PBX mode only) calls.
Selective Callback is also available.
Returning callback calls cancel Line Request.
Both Automatic and Selective Callback can be used from an MFM; a
callback call, however, cannot be manually canceled because the
MFM does not recognize the switchhook flash produced by pressing
the Drop button.
An outside caller waiting in the callback queue hears Music-On-Hold
if it is programmed.
Callback cannot be used for calls to a speakerphone paging group.
A voice-announced inside call that is queued using Callback
automatically becomes a ringing call. Systems with Loudspeaker
Paging can be set up to allow calls to be queued for the
Loudspeaker Paging system by placing the Loudspeaker Paging
jack in its own pool and having users access the paging system
through the pool. When the pool is busy, the call can be queued.
Calls waiting in a callback queue cannot be parked.
The Callback feature cannot be used to request a busy personal
line. See ''Line Request'' on page
A callback request cannot be picked up at another extension.
