1 Overview
1.1 Introduction
The GoIP series gateway is a broadband relay gateway newly developed by VOPTEL
Technology. It is a new product for seamless connection between the GSM network and VoIP
network. When the mobile phone SIM card is installed in the GoIP, users can register the
GSM phone to the VoIP softswitch system. Through the GoIP, users can realize the uplink and
downlink calls between the GSM network and the VoIP network. In addition, the GoIP
supports the transparent transmission of the caller number from the PSTN to the VoIP. The
GoIP features embedded SIP and H.323 protocols with flexible setting. The bi-directional
password authentication (call authorization) and trust list authentication greatly minimize the
risk of charge losses and the flexible routing function can meet special requirements of
various call forwarding. In particular, the GoIP gateway supports multi device groups, with
flexible setting of large GSM gateway groups with different channel numbers. With its low
price, excellent voice quality, and powerful features, the GoIP series gateway is the first
choice for system integrators, traffic operators, and softswitch manufacturers.
The GoIP series gateway includes GoIP-GSM, GoIP_4 and GoIP_8.

for centralized setting, technical support, and maintenance filing. The sequence number is
printed on the bottom plate of the gateway and is read-only.
B. Software Version
It displays the current version of software used by the GoIP. When you want to upgrade the

VOPTech GoIPUserManual
Voptel Technology Co., Ltd All Rights Reserved. 16
software, make sure the update version is newer than the current version.
C. Hardware Version
It displays the current hardware version of the gateway.
D. Line Register Status
It displays the login status of the line. When the line has logged into the SIP server or H.323
Gatekeeper, LOGIN is displayed, otherwise, LOGOUT is displayed.
E. Line Use Status
It displays the use status of the line. When the line is in use, the status is ACTIVE, when the
line is idle, the status is IDLE.

3.3.1 Language
To select a language, refresh the page to enter the language page required. For example, the
current language is simplified Chinese. If you wish to display the page in English, click
“English” in the menu. After your terminal is restarted, all the pages will be displayed in
English.
You can also use other languages for setting, as shown in the following figure.

VOPTech GoIPUserManual

Click “English” on the upper right corner of the setting page. Then, the setting page will
display all info in English. But the shortcut will not change the language of the setting page
when logged in next time.
3.3.2 Time Zone and Time Server
This item displays the adjusted time according to the selected time zone. The gateway receive
time and date information from the server through the Network Time Protocol and the time
difference will be automatically adjusted. For example, the pacific standard time (PST) is
GMT-8 and the pacific daylight time (PDT) is GMT-7.
The time zone indicates the zone where the gateway is used. You need to enter the correct
time zone, so that the time of the caller ID and charging information can be displayed
correctly. The time server is the address of the server that obtains the network time through
the Internet. The default time server is timekeeper.isi.edu.
3.3.3 DTMF Minimum Detection Interval
This parameter is used to set the minimum interval of two DTMF signals. Packets may be lost
during the data transmission over the GSM. As a result, a DTMF may be incorrectly identified
as two or multiple identical DTMFs when detected by the GoIP. The problem of repeated code
can be solved effectively through the modification of the parameter.
This parameter value ranges from 60ms to 120ms and the default value is 80ms. When the
value of this parameter is increased properly, the repeated DTMF can be avoided efficiently.
However, the packet loss may also be caused.
3.3.4 Automatic Setting
If the service provider provides the automatic setting, you can select “Enable” to start the

VOPTech GoIPUserManual
Voptel Technology Co., Ltd All Rights Reserved. 19
automatic setting feature and enter the address of the server. If the service provider does not
provide the automatic setting, you need to select “Disable” to speed up the startup time of the
GoIP.
It is a special server, which needs the support of the specific system.
3.3.5 Setting of the Remote Control
Press *20# on the terminal to initiate the request to realize the remote management of
equipment. The remote control server is provided by the service provider. The default port is
1920 and the terminal is identified by the SN. The remote control password is identical with
that of the server and is set as default.
In the following figure, the remote control server is set as 118.142.51.162. The terminal user
presses *20# and a long tone is heard, which indicates that the instruction has been
successfully sent. The remote administrator access http://118.142.51.162:8086 and the model
and SN of the gateway are displayed. Click the gateway SN to set the remote gateway.
Note: It is a special server, which needs the support of the specific system. For details, please contact the
technical support of VOPTEL Technology.
3.3.6 GSM Group Mode
Users can establish a GSM group containing multiple GoIP gateways. Under this mode, the
