11.15 Supplementary Phone Services Overview

Supplementary services such as call hold, call waiting, call transfer, … are generally available

from your VoIP service provider. The ZyXEL Device supports the following services:

• Call Hold

• Call Waiting

• Making a Second Call

• Call Transfer

• Call Forwarding (see Section 11.19 on page 174)

• Three-Way Conference

• Internal Calls (see Section 12.3 on page 179)

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.

11.15.1 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.

11.15.2 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.

Table 60 European Flash Key Commands
