2.3 IP Environment Setting
User must prepare a valid IP address to be complied IP Network policy in
order for VoIP FXO gateway operating correctly.
For example, if your company’s IP address is 192.168.4.111, subnet mask is
255.255.0.0, default gateway is 192.168.1.254, you should prepare one IP for
VoIP FXO gateway, such as IP address is 192.168.4.99, and same subnet
mask and default gateway.

3. Login: when VoIP FXO gateway is used for the first time, “root” is default
login name without a password.
4. Password setting: type “passwd –set root ****” to define a password for
“root” account. “****”, in above description, stands for contents of the
password. An example, to set root’s password as good, is demonstrated
as following:
usr/config$ passwd -set root good
Setting
login: root
Password: good
OK

12
(b) Configure VoIP FXO gateway IP Address
Use “ifaddr” command to set up VoIP FXO gateway’s IP address and related
network information. An example is demonstrated below:
usr/config$ ifaddr –ip 10.1.1.1 –mask 255.2555.255.0 –gate 10.1.1.254
Note:
this is to assign VoIP FXO gateway an IP address of “10.1.1.1”, subnet mask
“255.255.255.0”, and default IP gateway “10.1.1.254”.
(c) Gatekeeper Mode Settings
To assign a gatekeeper address for VoIP FXO gateway, and define its own
registered ID and phone number. For detail, please refer to Chapter 5.14
[h323] command.
Several H323 parameters are important setting gatekeeper mode:
“–gk”, ”–e164”, and ”–alias”. An example is demonstrated below:
usr/config$ h323 –mode 0 –gk 10.2.2.2 –e164 –alias fxo
Note:
This is to set mode as gatekeeper mode, gatekeeper IP address as “10.2.2.2”,
e.164 number as “1”, and alias name (h323ID) as “fxo” on the VoIP FXO
gateway.
(d) Save VoIP FXO Gateway Configuration & Reboot VoIP FXO gateway
1. Confirming the values, type commit and press enter to save all the
changes you have done.
2. Type reboot and press enter to reboot the VoIP FXO gateway.
3. Wait for VoIP FXO gateway initializing in gatekeeper mode.
3.2 Peer-to-Peer Mode
Peer-to-Peer Mode allows users to call other VoIP devices without using a
gatekeeper. When in Peer-To-Peer mode, VoIP FXO gateway will send
SETUP message directly to the destination IP address once the dial is
finished. Users have 2 methods of dial. One is IP dialing, and the other is
phone book dial, which we will describe later. When using IP address as
destination phone number, press “*” as “.” in IP address expression, and press
“#” when dial is finished. When using Phone book, users can dial predefined
phone number, and press “#” (optional, to accelerate the dial) as end of dial.
To configure Peer-To-Peer Mode in VoIP FXO gateway, follow the steps
below:
1. Set Peer-To-Peer Mode, using “h323” command
usr/config$ h323 –mode 1

13
Note: mode 1 is for Peer-To-Peer (non-gk) mode, while mode 0 is for GK
mode.
2. Configure Phonebook, using “pbook” command.
Users can refer to chapter 5.11 [pbook] command for more information.
usr/config$ pbook –add name TEST1 ip 10.1.1.1 e164 10
Note:
The command is to add a record onto Phonebook. After the command
completed, you can type “pbook –print” to see if the input record is correct.
When adding a record to Phonebook, users do not have to reboot the
machine, the record will be effective immediately.
3.3 Behind IP-Sharing
The function is for user whose network environment is behind IP Sharing
device. It is said VoIP FXO gateway is connected to the IP Sharing device. An
example such as ADSL network is in the following.
ATU-R ADSL Modem
WAN
IP Sharing device
LAN LAN
VoIP FXO gateway PC
zThe WAN IP address obtained from ADSL has two kinds of methods. One
is fixed IP Address, while user applies for one or more fixed IP Addresses.
Another is dynamic IP Address while user applies for dial-up connection
way.
zThe LAN IP address of user’s PC can be set as DHCP client in order to
gain an valid one.
zAnther IP address for VoIP FXO gateway must be set as an fixed one in
order for that IP sharing device pass forwarding the relevant information
from WAN to LAN. Besides, a valid IP address which meets the IP
sharing device (LAN site) is the element.
zVoIP FXO gateway must enable the IP sharing function for the fixed /
dynamic WAN IP Address.
Fixed IP Address – usr/config$ ifaddr –ipsharing 1 210.11.22.33

14
Dynamic IP Address –usr/config$ ifaddr –ipsharing 1
Note:
With Dynamic WAN IP Address, a Gatekeeper with a valid IP address for VoIP
FXO gateway is a must. In other word, it is not workable in Peer-to-Peer mode
while dynamic WAN IP Address.
IP Sharing device must have a function to do IP/Port mapping. Some is
named as DMZ, some is named as virtual server. The VoIP messages from
WAN have to completely pass forward to the LAN. It is said if the VoIP FXO
gateway is assigned a virtual fixed IP Address such as 192.168.1.5, IP sharing
device must forward the VoIP messages to 192.168.1.5.

4. Disconnect Tone Configuration
This application note is going to describe the procedures of configuring the
disconnect tone on VoIP FXO gateway in order to release LINE ports of VoIP
FXO gateway after PSTN/PBX caller party is hung up.
4.1 What is Disconnect Tone
A caller make a telephone call to gateway from PSTN side, VoIP FXO
gateway will answer the call automatically. If the IP side of other VoIP devices
do not answer the call and the caller hang up the call, the PSTN/PBX will give
gateway a disconnect tone automatically. Or, VoIP FXO gateways are
installed on both sied and connect to local PSTN. If both parties are in talking
mode and one side hang up the call. the VoIP FXO gateway has to recognize
the disconnect tone from local PSTN and release the line port with the
pre-defined busy tone or reorder tone in VoIP FXO gateway tone table.
There are three parameters received from PSTN/PBX.
-High level frequency and Low level frequency
-Tone Cadence (ON/OFF intervals)
-Tone level
These parameters have to be properly configured in VoIP FXO gateway in
order to recognize disconnect tone correctly. Each different PSTN/PBX have
different parameters. So, VoIP FXO gateway has to configure tone table when
line port connect to different PSTN/PBX.
4.2 How to configure disconnect tone on VoIP FXO gateway
VoIP FXO gateway has a default setting of disconnect tone (Busy tone 1,
Busy tone 2, reorder tone 1 and reorder tone 2 ). If the disconnect tone was
recognized correctly, the line port from PSTN/PBX will be released in seconds.
IP-Network
PSTN or
PBX
VoIP
FXO
gateway
Other VoIP
devices
IP Side PSTN side
Caller

16
Otherwise it may be released after one minute or lock this LINE permanently.
The tone table parameters are shown as follows.
LowFreq 480 : Low frequency is 480 HZ
HighFreq 620 : High frequency is 620 HZ
LowFreqLevel 8 : Low frequency level received range from PSTN/PBX
HighFreqLevel 8 : High frequency level received range from PSTN/PBX
TOn1 50 : Disconnect tone cadence ON time is 0.5 seconds
TOff1 50 : Disconnect tone cadence OFF time is 0.5 seconds
( If this is continuous tone, the Toff has to set to 1023 )
TOn2 1023 : Disconnect tone second cycle cadence ON time is OFF
TOff2 1023 :Disconnect tone second cycle cadence OFF time is OFF
( If the tone cadence has only one cycle, the second cycle must set to 1023 )
(1) Examples how to configure Tone table
a. 480/620 frequency with ON/OFF time is 0.5 seconds
tone -busy1 480 620 8 8 50 50 1023 1023
b. 480 HZ single frequency with continuous tone
tone –reorder2 480 0 8 0 50 1023 1023 1023
(2) There are two ways to analyze the disconnect tone.
a. The first one is using command “greetrd” from VoIP FXO gateway. Once
you follow the instruction to analyze the disconnect tone, gateway will
configure the tone table (Busy tone 1, Busy tone 2, reorder tone 1 and
reorder tone 2 ) with proper frequency and default tone level and cadence
(Ton1/Toff1) automatically. Or you may read the analysis tone frequency
from command line and configure to one of tone table manually.
The default tone level is set to 8. And the tone cadence (Ton1/Toff1) is set
to four different values on tone table. They are 0.1 second, 0.25 seconds,
0.5 seconds and 0.75 seconds with parameters 10/10, 25/25, 50/50 and
75/75.
If the PBX/PSTN cadence is not the value as default shown as above, you
need to use the following instruction to analyze ON/OFF intervals.
b. You may use your PC (START ÆProgram Files ÆAccessories Æ
Multimedia ÆRecorder) with Headset or Microphone to record the
disconnect tone via a telephone set from PSTN/PBX and save to a voice
file. Then you can use “CoolEdit Pro” software to analyze the frequency
and ON/OFF time. Please visit http://www.cooledit.com to download demo
version for analysis. You can use this program to analyze ON/OFF time
and fill in to tone table.
4.3 Adjust Tone Table parameters manually
If the gateway still cannot release the LINE port in two seconds, try to adjust
the frequency by 1 hz on tone table. For example, your analysis value is

17
620/480, take the following procedures.
620/479
620/480
620/481
621/479
621/480
621/481
619/479
619/480
619/481
If the line port of gateway was locked, please use “hangup 0” command to
release LINE 1, “hanhup 1” to release LINE 2…etc.
4.4 Adjust Input Tone Level
Sometimes the disconnect tone level is too low to be detected by VoIP FXO
gateway. You can increase input gain from the following command.
voice -volume input xx
commit
reboot
xx is the input gain parameters. The maximum number is 35. if the number is
over 35, the echo may be happened. Once you increase input gain, the voice
volume from PSTN to IP side is increased too.
