11.7.1 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 manual tapping, if the duration is too long, it
may be interpreted as hanging up by the ZyXEL Device.
You can invoke all the supplementary services by using the flash key.
