Flash:
It is used for putting the calling party on hold during an internal or external call. When it
is pressed for a second time, the call on hold is retrieved, or the call can be retrieved by
the “Retrieve” option that appears when the key is pressed.
It drops the line when it is used while the other party has not yet picked up the phone. A
single call can be put on hold at a time. There is no limit for the duration to press the
key; however, in the event that the line that has been put on hold has not still be
retrieved at the end of a certain period that is determined by the exchange software,
the line may automatically be dropped.
Transfer:
It is used for transferring an ongoing call to another call that is on hold. In order to
actualize the transfer operation, first of all the conversing party should be put on hold
by using the flash key or the “Hold” / “Park” option on the display. Afterwards, the
number to which the transfer operation will be done is dialed. At this point, the
operation is accomplished by pressing the transfer key before or after conversing with
the extension to which the call is to be transferred.
During a “Transfer” operation done via ST26/DS200:
·
A line cannot be transferred to another line.
·
If it is the ST26 user who has started the conversation, then an extension cannot
be transferred to a line.
·
On the other hand, if it is a line that has started the conversation, then that line can
be transferred to an extension.
Making use of the transfer option on the LCD display will also accomplish the transfer
operation following the same rules above.
Redial:
It dials again the last number that has been dialed. This key functions the same way as
the “Redial” option on the display. The difference between “Redial” and “Auto-dial” is
that the “Auto-dial” option automatically calls the other party repeatedly until busyness
status is over (Actually, at most 16 times), whereas the “Redial” option calls only once.
When the “Redial” option is used, the line access code and the dialed number are
displayed together on ST26 display.
