Note: To take full advantage of the supplementary phone services available though
the ZyXEL Device's phone port, you may need to subscribe to the services
from your VoIP service provider.
11.1.3.1 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. The ZyXEL Device may interpret manual tapping as
hanging up if the duration is too long
You can invoke all the supplementary services by using the flash key.
11.1.3.2 Europe Type Supplementary Phone Services
This section describes how to use supplementary phone services with the Europe Type Call
Service Mode . 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.
11.1.3.2.1 European Call Hold
Call hold allows you to put a call ( A ) on hold by pressing the flash key.
