In Release 4.1 and later systems, if all SA or ICOM buttons are busy at
the forwarding extension, the call is automatically forwarded.
In Release 4.0 and prior systems, if all SA or ICOM buttons are busy at
the forwarding extension, the caller hears busy tone and the call is not
forwarded. In this situation, 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.
Group Calling 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.
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.
Headset Options 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.
Hold 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.
HotLine 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.
Line Request Returning callback calls cancel Line Request.
Multi-Function
Module
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.
Music On Hold An outside caller waiting in the callback queue hears Music On Hold if it is
programmed.
Paging 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.
