Recall 2 - 8 - AT&T SYSTEM 25 Manual

Users of single-line voice terminals that have a RECALL button 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. For
more information about this feature, see the entry for "Callback Request" on page 2-11. 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.
