27.5.4 Backup Configuration Using TFTP

The ZyXEL Device supports the up/downloading of the firmware and the
configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Although
TFTP should work over WAN as well, it is not recommended.

P-2612HWU-F1 User’s Guide

453

Chapter 27 Tools

T o use TFTP, your computer must have both telnet and TFTP clients. To backup the
configuration file, follow the procedure sh own next.

1 Use telnet from your computer to connect to the ZyXEL Device and log in. Because

TFTP does not have any security checks, the ZyXEL Device records the IP address
of the telnet client and accepts TFTP requests only from this address.

2 Enter command “sys stdio 0” to disable the management idle timeout, so the

TFTP transfer will not be interrupted. Enter command “sys stdio 5” to restore
the five-minute management idle timeout (default) when the file transfer is
complete.

3 Launch the TFTP client on your computer and connect to the ZyXEL Device. Set

the transfer mode to binary before starting data transfer.

4 Use the TFTP client (see the example below) to transfer files between the ZyXEL

Device and the computer. The file name for the configuration file is “rom-0” (rom-
zero, not capital o).

Note that the telnet connection must be active before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult
the documentation of your TFTP client program. For UNIX, use “get” to transfer
from the ZyXEL Device to the computer and “binary” to set binary transfer mode.

27.5.5 TFTP Command Configuration Backup Example

The following is an example TFTP command:

tftp [-i] host get rom-0 config.rom

where “i” specifies binary image transfer mode (use this mode when transferring
binary files), “host” is the ZyXEL Device IP address, “get” transf ers the file source
on the ZyXEL Device (rom-0, name of the configuration file on the ZyXEL Device)
to the file destination on the computer and renames it config.rom.

I can access the Internet, but cannot make VoIP calls.

1 The PHONE light should come on. Make sure that your telephone is connected to

the PHONE port.

2 You can also check the VoIP status in the Status screen.

3 If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you

can make a call using speed dial, there may be something wrong with the SIP
server, contact your VoIP service provider.

29.6 Multiple SIP Accounts

You can set up two SIP accounts on your ZyXEL Device and your ZyXEL Device is
equipped with two phone ports. By default yo ur ZyXEL Device uses SIP account 1
with both phone ports for outgoing calls, and it uses SIP accounts 1 and 2 for
incoming calls. With this setting, you always use SIP account 1 for your outgoing
calls and you cannot distinguish which SIP account the calls are coming in
through. If you want to control the use of different dialing plans for accounting
purposes or other reasons, you need to configure your phone ports in order to
control which SIP account you are using when placing or receiving calls.

connection. It allows your ISP to use their existing network
configuration with newer broadband technologies such as ADSL.
The PPPoE driver on your device is transparent to the computers
on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPP oE clients on individual
computers.

Call park and pickup lets you put a call on hold (park) and then
continue the call (pickup). The caller must still pay while the call is
parked.

When you park the call, you enter a number of your choice (up to
eight digits), which you must enter again when you pick up the call. If
you do not enter the correct number, you cannot pickup the call. This
means that only someone who knows the number you have chosen
can pick up the call.

You can have more than one call on hold at the same time, but you
must give each call a different number.

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

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).

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.

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.

You can simultaneously use multiple voice (SIP) accounts and assign
them to the telephone port.

Your device can simultaneously handle multiple voice channels
(telephone calls). Additionally you can answer an incoming phone call
on a VoIP account, even wh ile someone else is using the account for a
phone call.

Voice Activity Detection (V AD) reduces the bandwidth that a call uses
by not transmitting when you are not speaking.

Your device generates background noise to fill moments of silence
when the other device in a call stops transmitting because the other
party is not speaking (as total silence could easily be mistaken for a
lost connection).

echo caused by the sound of your voice reverberating in the
telephone receiver while you talk.

Quality of Service (QoS) mechanisms help to provide better service
on a per-flow basis. Your device supports Type of Service (ToS)
tagging and Differentiated Services (DiffServ) tagging. This allows
the device to tag voice frames so they can be prioritized over the
network.
