3 Configuration Guide
To configure the GoIP Gateway, you must login to its Web server via the LAN or PC port.
The LAN port is factory preset to obtain an IP from the local DHCP host and the PC port is
set to the fixed IP 192.168.8.1.

One Chunnel GSM VoIP Gateway

If a local DHCP host is available, the LAN will obtain an IP address automatically. To listen
to the IP address assigned, just dial a call via the GoIP Gateway’s SIM card phone
number. When the call is connected, you will hear a dial tone. Just dial “*01#” for English
voice prompt on the LAN IP and “*00#” for Chinese voice prompt on the LAN IP. The LAN
IPAddress can also be obtained by sending a SMS message to the GSM phone number.
The GoIP will then reply with a SMS message containing the LAN IP address.
If you want obtained LAN port IP by sending a SMS message, please send” INFO “or”
info”.
If a local DHCP host is not available, you can then access the GoIP Gateway via the PC
port. You will need to change the PC LAN configuration via the Network Connections
under the Control Panel.
Windows: Control Panel--ÆNetwork Connections--ÆLocal
Connectionism’s Property--ÆTCP/IP Protocol’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 GoIP Gateway.
3.1 Web Configuration Menu
If your PC is connected to the GoIP Gateway via the LAN port network segment, you need
to type the LAN IP address of the GoIP Gateway in your Web Browser to access the Web
server of the GoIP Gateway. If not, you should type the PC IP address (192.168.8.1) in

Each tone listed above is defined in the following format:
nc, rpt, c1on, c1off, c2on, c2off, c3on, c3off, f1, f2, f3, f4, p1, p2, 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)
c2on is the cadence two on (in milliseconds)
c2off 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)
f2 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)
p2 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 1,0,700,1000,0,0,0,0,450,0,0,0,20,0,0,0
