Automatic Recall A-8
A-8 Automatic Recall
General Description
This feature works as a timed reminder. When a call handled by the Attendant remains on hold, camped-on, or
ringing unanswered for a fixed interval, the Attendant is automatically alerted.
Operating Procedure
No manual operation is required.
Service Conditions
1. AUTOMATIC RECALL [A-8] timing is preset in system data at 30 seconds. See VARIABLE TIMING
PARAMETERS
[V-1] for other selectable timing choices.
2. If the Attendant reenters a held or camped-on trunk, timing is reset when the trunk is returned to the
previous condition.
3. The Attendant Console buzzer will sound to signal Recall, provided no calls are being processed, in
addition to the standard visual indication for incoming calls.
4. This feature is denied on INCOMING CENTRAL OFFICE CALL TO TIE LINE CONNECTION [I-3].
5. When an Attendant answers AUTOMATIC RECALL, either the dialed number or the calling telephone/
trunk number can be displayed (on system data basis).
6. The indication on the ATTENDANT CONSOLE [A-3] follows DIGITAL DISPLAY - STATION [D-5].
When the dialed number (destination) is displayed, the display is as follows:
Tenant Number: Blank Space
Trunk Route Restriction Class: Blank Space
Telephone Number: Dialed Number (Last Digits)
Interactions
1. This feature is available on calls extended to a branch PBX via a CENTRALIZED ATTENDANT
SERVICE [C-20] (CAS) position.
2. System Data 2, Index 6, Bit 7. On a per-tenant basis, allow this Bit for CALL FORWARD - DON’T
ANSWER [C-2] via the Attendant Console. During this operation, the call will ring at the called station
for the time interval set in System Data 1, Index 141 (ASYD 145 must be longer than 141). The call is then
forwarded and rings at the forwarded station for the time interval set in Index 145. If the call is still not
answered, it will be recalled to the Attendant Console via the AUTOMATIC RECALL feature.
3. System Data 1, Index 70, Bit 0 (Called Number Display). This Bit does not affect the display on the
Attendant Console for recalled calls. It is used for DIDs that have call forwarded to the Attendant or if the
Attendant reenters the loop on an extended call before AUTOMATIC RECALL has taken place.
4. When a trunk call recalls back to the Attendant Console, the destination telephone number will display,
and the SOURCE (SRC) LED will be lit. By pressing the SRC key, the display will change to the
originating route and trunk number. By pressing the DEST key, the display will change to the destination
station.
5. The station will continue to ring even as the call recalls to the Attendant Console. If the station should
answer at the same time the Attendant answers the recalling call, a three-way conversation will take place
(if conferencing is allowed and a conference card is programmed and installed). The Attendant can press
the SRC, DEST, or TALK keys to achieve the desired conversation or press the RELEASE key to get out
of the conversation.
