Chapter 13 Supplementary Phone Services
13.2 Setting Up Supplemental Phone Service
All Supplemental Phone Services are enabled by default except for Call Waiting, which is
disabled by default but can be enabled in SMT Menu 2.1 - ISDN Advanced Setup. The
Calling Line Indication, or Caller ID, also in this menu decides whether the other party can
see your number when you call. If set to Enable (default), the ZyXEL Device sends the caller
ID and the party you call can see your number, otherwise if set to Disable, the caller ID is
blocked.

13.3 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.
