Note: 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.

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. 

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.

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.
