Introducing the Ozeki VoIP GSM Gateway
The Ozeki VoIP GSM Gateway is a device that lets you make\receive Voice calls and
send\receive SMS messages through the mobile telephone network. This is a 4 channel
device. It means 4 simultanous calls can take place at the same time. This
product has been tested and it works well with Ozeki VoIP products, such as
Ozeki VoIP SIP SDK,
Ozeki NG SMS Gateway or
Ozeki Phone System. It can
also be used to notify system administrators through automated Voice Calls when
server breakdowns happen if you use the Ozeki Cluter software to achieve better uptimes.
Please check out the following video to learn more about the Ozeki VoIP GSM Gateway.

1. What you need
In order to make calls from one of our software through a GSM network you need to connect the Ozeki VoIP GSM Gateway and our software together and you need to insert a SIM card into the Ozeki VoIP GSM Gateway. In the Figure 1 you can see the accessories:
- SIM card: It is used to provide a connection to a GSM service provider. You can buy it directly from a GSM service provider.
- Ozeki VoIP GSM Gateway: It can be used between the GSM network and a few Ozeki software. It is a gateway that allows you to make calls toward the Public Switched Telephone Network from the VoIP phone network. You canorder it directly from Ozeki.
- A communication software: For example Ozeki Dialer. It is a SIP VoIP software. It allows you to make calls toward the GSM network with the help of Ozeki VoIP GSM Gateway. You can order it directly from Ozeki.
2. Opening the box
After you have received the Ozeki VoIP GSM Gateway package (you can see it in Figure 2) unpack the box.
The Figure 3 shows the opened box with its content.
Take the accessories out of the box then you check them. The Figure 4 shows what you can find in the box (from right):
- 1× Ozeki VoIP GSM Gateway
- 1× DC Power Adapter
- 1× Ethernet cable
In addition you can see a mini-SIM card (25.00 mm × 15.00 mm × 0.76 mm) that will be inserted into a SIM card slot (Figure 3 on the left).
3. Connecting the DC Adapter and a SIM card to each other
After that, you need to connect the Ozeki GSM Gateway to a plug, to the computer network and you need to put one-four SIM card(s) into the device.
The Figure 5 shows the slots where the SIM cards and the DC adapter have to be plugged.
- The DC adapter is plugged into the rightmost connector that is signed with a DC12V label.
- The SIM cards are plugged into the slots which are located between the Channel 1-4 labels and the antennas. The chip on the SIM card has to see up when you put it into the slot.
After you have inserted the SIM cards into the slots you need to push it while a click is not listened (Figure 6).
4. Connecting the Ozeki VoIP GSM Gateway to a computer
If the SIM card and DC adapter have been plugged, you need to connect the Ozeki GSM Gateway to a computer to set the IP address of the device.
To connect a gateway and a computer to each other you need to use a straight-through Ethernet cable (the yellow cable on Figure 7). One of the ends of the cable has to be plugged into the Ethernet port of the computer and the other has to be plugged into the PC port of the Ozeki VoIP GSM Gateway.
Now you can configure the Ozeki VoIP GSM Gateway in a web browser.
By default the IP address of the gateway's PC port is 192.168.8.1. To reach the graphical user interface of the device you need to set an IP address on the Ethernet port of the computer that is in the same network. The IP address of the PC can be from the range of 192.168.8.2 - 192.168.8.254.
5. Network settings in the Ozeki VoIP GSM Gateway
Open a web browser, such as Internet Explorer and enter http://192.168.8.1 in the address bar. Then the login page is popped up (Figure 8) to give the username in the User Name and password in the Password field (root username: admin; root password: admin).
After you have clicked on the Ok button, the Status page will appear. To set the IP address of the gateway, click on the Configurations and Network links. The Figure 9 shows what you need to set on the LAN port:
- LAN port mode: Static IP.
- IP address: An address from the network to which you would like to connect the gateway.
- Subnet mask: The proper mask that belongs to the connected network.
- Default route: The IP address of the default gateway. This is the IP address of that router's interface which is connected to the local computer network.
- Primary DNS: The IP address of the domain name server that is responsible for assigning the IP addresses and the domain names.
Then click on the Save Changes and follow the below instructions:
- Connect the gateway to the local computer network through the LAN port of the device (Figure 10).
- Disconnect the computer from the gateway and connect it back to the local computer network.
- Set the IP address of the computer back.
After doing these settings, you can configure the Ozeki VoIP GSM Gateway from any computer in the same computer network. Just type the previously set IP address to the web browser, give the login data and you can configure it from anywhere.
6. What do you need to setup in the graphical user interface of the Ozeki VoIP GSM Gateway
If you have inserted the SIM cards into the Ozeki VoIP GSM Gateway, you can see the status of the SIM cards.
In the Figure 11 you can see that there are three SIM cards, which are inserted into the gateway and they are logged in successfully.
In Figure 12 you can see the VoIP settings.
From the Config mode menu you need to select the Single Server Mode option. On the right side of this menu, click on the SIP Advanced Settings link. Then choose the None option from the VoIP to PSTN Auth Mode and click on the Save settings button.
