To take full advantage of the supplementary phone services available through 
the ZyXEL Device's phone ports, you may need to subscribe to the services 
from your VoIP service provider.
11.11.1  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. 
11.11.2  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.
11.11.2.1  European Call Hold
Call hold allows you to put a call (A) on hold by pressing the flash key.
