FEATURES AND SERVICES
Recall
Description
Users of single-line voice terminals that have RECALL buttons can obtain System 25 recall
dial tone by pressing the button. Pressing RECALL is equivalent to briefly pressing and
releasing the switchhook (switchhook flash), which is the required method of getting recall
dial tone at a terminal not equipped with the RECALL button.
Multiline voice terminals are administered for either manual or automatic activation of the
Callback Queuing feature. Operation of the RECALL button is the manual method. Refer to
the “Callback Queuing” feature description for complete information. Use of the RECALL
button for callback does not interfere with its Centrex functions, described in the next
paragraph.
The RECALL button on a multiline voice terminal can be used, under specialized conditions,
to send a switchhook flash to the Central Office (for example, to access Centrex services).
However, it can never be used to send a switchhook flash to the System 25.
Interactions
The following feature interacts with Recall.
Callback Queuing: The RECALL button can be used to send switchhook flash to Centrex
trunks. If a conference exists with a queuable tone and a Centrex trunk, the first push of
RECALL queues the call. A second push of RECALL is needed to send switchhook flash to
the Central Office.
Administration Requirements
For Centrex operation, stations must not be assigned toll restriction, and the Centrex trunks
must be administered as Type 805.
