In a case where no pools are available and an inside caller is not using
Automatic Callback, a call to an extension with Remote Call Forwarding
follows the extension's coverage path. 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.
Calls made to a calling group are not eligible for Callback because the
calls ring into the calling group's queue. However, Callback can be used
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.
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 flashes next to the line button, indicating that
the button is being used for the queued call.
Callback is not intended for HotLine extensions (Release 5.0 and later
systems). However, Automatic Callback may 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;
however, a callback call 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.
