Country Code Phone standards and settings differ from one country to another, so the settings
on your ZyXEL Device must be configured to match those of the country you
are in. The country code feature allows you to do this by selecting the country
from a list rather than changing each setting manually. Configure the country
code feature when you move the ZyXEL Device from one country to another.
Distinctive Ringing With the distinctive ring feature, you can assign different ringing tones to
different incoming calls, based either on the number that calls you or from
where the call originates (SIP, PSTN or internal). Use this feature to let you
know where a call comes from before you answer it.
Do not Disturb
(DnD)
This feature allows you to set your phone not to ring when someone calls you.
You can set each phone independently using its keypad, or configure global
settings for all phones using the command line interpreter.
Hot Line You can set the ZyXEL Device to automatically dial a specified number
immediately whenever you lift a phone off the hook. Use the Web Configurator
to set the specified number. Use the command line interpreter to have the
ZyXEL Device wait a specified length of time before dialing the number.
Music on hold This feature allows you to put a call on hold and have the other person hear a
piece of audio (music, speech, etc.) you previously recorded.
Phone config The phone config table allows you to customize the phone keypad combinations
you use to access certain features on the ZyXEL Device, such as call waiting,
call return, call forward, etc. The phone config table is configurable in command
interpreter mode.
Internal call When you have phones attached to both of the ZyXEL Device’s phone ports,
you can dial “####” to call all the phones connecting to the ZyXEL Device’s
phone ports. You can also assign each phone connected to the ZyXEL Device
an extension number and place a internal call to a specific phone.
HTTP Pincode When new firmware is available for your ZyXEL Device, you hear a recorded
message when you pick up the phone. Enter *99# in your phone’s keypad to
have the ZyXEL Device upgrade the firmware, or enter #99# to not upgrade. If
your service provider gave you different numbers to use, enter them instead. If
you enter the code to not upgrade, you can make a call as normal. You will hear
the recording again each time you pick up the phone, until you upgrade.
Call waiting This feature allows you to hear an alert when you are already using the phone
and another person calls you. You can then either reject the new incoming call,
put your current call on hold and receive the new incoming call, or end the
current call and receive the new incoming call.
Call forwarding With this feature, you can set the ZyXEL Device to forward calls to a specified
number, either unconditionally (always), when your number is busy, or when
you do not answer. You can also forward incoming calls from one specified
number to another.
Caller ID The ZyXEL Device supports caller ID, which allows you to see the originating
number of an incoming call (on a phone with a suitable display).
Trunking Trunking connects an IP network (like the Internet) with the regular telephone
network (PSTN). The main advantage of trunking is that you can call your
ZyXEL Device on the PSTN network, and then use it to make a VoIP phonecall.
For example, if you have a ZyXEL Device at your office you can call into it from
your cellphone and use it to make a long-distance or international VoIP call at a
reduced cost.
REN A Ringer Equivalence Number (REN) is used to determine the number of
devices (like telephones or fax machines) that may be connected to the
telephone line. Your device has a REN of three, so it can support three devices
per telephone port.
Dynamic Jitter
Buffer
The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for
voice traffic. This helps ensure good voice quality for your conversations.
