2.12.4.1 The Flash Key
Flashing means to press the hook for a short period of time (a few hundred milliseconds)
before releasing it. On newer telephones, there should be a "flash" key (button) that generates
the signal electronically. If the flash key is not available, you can tap (press and immediately
release) the hook by hand to achieve the same effect. However, using the flash key is
preferred since the timing is much more precise. With manually tapping, if the duration is too
long, it may be interpreted as hanging up by the TA.
You can invoke all the supplementary services by using the flash key. Commands for
supplementary services are listed in the table below
After pressing the flash key, if you do not issue the sub-command before the default sub-
command timeout (2 seconds) expires or issue an invalid sub-command, the current operation
will be aborted.
2.12.4.2 Call Hold
Call hold allows you to put a call (A) on hold by pressing the flash key.
If you have another call, press the flash key and then “2” to switch back and forth between
caller A and B by putting either one on hold.
Press the flash key and then “0” to disconnect the call presently on hold and keep the current
call on line.
Press the flash key and then “1” to disconnect the current call and resume the hold call.
If you hang up the phone but a caller is still on hold, there will be a remind ring (see Section
4.1.1 on page 68 for more information).
