3 Configuration Guide
To configure the GoIP4 Gateway, you must login to its Web server via the LAN or PC port.
The LAN port is factory preset to IP address 192.168.0.100 and the PC port is set to the fixed
IP 192.168.8.1.
If you lose the IP address information for LAN port, just dial a call to GoIP4 Gateway’s SIM
card phone number. When the call is connected, you will hear a dial tone. Then dial “*01#”
for English voice prompt on the LAN IP and “*00#” for Chinese voice prompt on the LAN IP.
The LAN IP Address can also be obtained by sending a SMS message to the GSM phone number.
The GoIP4 will then reply with a SMS message containing the LAN IP address.
If you want to obtain LAN port IP by sending a SMS message, please send” I FO “or” info”.
Another way to access the GoIP4 Gateway is via the PC port. You will need to change your
computer’s LAN configuration via the Network Connections under the Control Panel.
Windows: Control Panel--Network Connections--Local Area
Connection Property--

 Internet Protocol (TCP/IP)’s Property
Set an unused IP address that is in the same segment as the PC port address.
Once either the IP address of the LAN or PC port is known, you are now ready to
access the Web server of GoIP4 Gateway.

3.1 Web Configuration Menu
If your computer is connected to the GoIP4 Gateway via the LAN port, you need to type the
LAN IP address of the GoIP4 Gateway in your Web Browser to access the Web server of the
GoIP4 Gateway. The default IP address on the LAN port is “192.168.0.100”.
If your computer is connected to the GoIP4 Gateway via the PC port, you should type GoIP4’s
PC port IP address (192.168.8.1) in the Web Browser.
If the connection is correct, the Web Browser will prompt you to enter the “User name” and
“Password” as shown below. Enter the User name and Password and the press OK to access
the GoIP4 Gateway Web Server. The default for both user name and password is “admin”.

3.3. Time Zone and Time Server
The GoIP4 Gateway supports Network Time Protocol (NTP) to obtain the date and time
information from an NTP server (Time Server). The time zone is specified as in GMT ± offset.
For example, the Pacific Standard Time is GMT-8, and the Pacific Daylight Time is GMT-7.
Note: The GoIP4 Gateway supports CDR and Billing Information, it is important to set up
these two parameters properly.
3.3.3 DTMF Min Detect Time Gap
This parameter is used to limit two same DTMF digit’s minimum time gap, the range is 60ms
to 120ms, default is 80ms.
If you encounter double digit problem, increase this parameter. If you encounter lose digit,
then decrease this parameter.
3.3.4 Network Tone
Network Tones are a set of tones used for VoIP calls. Select one of the predefined countries
or select “Customized” to define your own Network Tones.
You can configure the Network Tones as Customized option:

Four-Channel GSM VoIP Gateway
17
Each tone listed above is defined in the following format:
nc, rpt, c1on, c1off, c on, c off, c3on, c3off, f1, f , f3, f4, p1, p , p3, p4
Where:
nc is the number of cadences
rpt is the repeat counter(0 - infinite, 1~n - repeat 1~n times)
c1on is the cadence one on (in milliseconds)
c1off is the cadence one off (in milliseconds)
c on is the cadence two on (in milliseconds)
c off is the cadence two off (in milliseconds)
c3on is the cadence three on (in milliseconds)
c3off is the cadence three off (in milliseconds)
f1 is the tone #1 frequency (300Hz-3000Hz)
f is the tone #2, frequency (300Hz-3000Hz)
f3 is the tone #3 frequency (300Hz-3000Hz)
f4 is the tone #4 (300Hz-3000Hz)
p1 is the attenuation index for f1, 0~31(0=3dB, -1dB increments)
p is the attenuation index for f2, 0~31(0=3dB, -1dB increments)
p3 is the attenuation index for f3, 0~31(0=3dB, -1dB increments)
p4 is the attenuation index for f4, 0~31(0=3dB, -1dB increments)
For example, the tone definition for a tone of 450Hz with a cadence of 700 ms on and 1000
ms off is 1,0,700,1000,0,0,0,0,450,0,0,0, 0,0,0,0
