How to enable the SMPP server functionality of Ozeki VoIP GSM Gateway
When a SIM card is inserted in the Ozeki VoIP GSM Gateway, it is possible to send or receive SMS messages with any SMPP client using the GSM Network (Figure 1). You only need to enable the SMPP server functionality of Ozeki VoIP GSM Gateway and your SMPP client software can connect to it via LAN or WAN.
STEP 1: Connect Ozeki VoIP GSM Gateway to your computer
First you need to connect the Ozeki VoIP GSM Gateway to a computer to start the configuration of the device.
To connect a gateway and a computer to each other you need to use a straight-through Ethernet cable. 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.
STEP 2: Login to Ozeki VoIP GSM Gateway
Open a web browser, such as Microsoft Edge and enter http://192.168.8.1 in the address bar. Then the login page is popped up (Figure 2) to give the username in the User Name and password in the Password field (root username: admin; root password: admin).
STEP 3: Enable SMPP SMSC functionality
After you have successfully logged in to the configuration page of the gateway, you need to enable the SMPP SMSC (SMPP server) functionality of the gateway. The following figure shows you how to enable it.
First click on the Preferences submenu under the Configurations menu. Then on the right section of the webpage, enable the checkbox belonging to SMPP SMSC. Below this checkbox, you need to fill three textboxes:
If you wish to connect your SMPP client to the gateway, you need to provide these data in your SMS software:
STEP 3: Configure number plan
If you have a gateway with 2 (or more) SIM cards, you can create number plans to control which SIM card will send which SMS message.
Click on SMS submenu under Configurations menu. CH1, CH2, CH3 and CH4 indicates which SIM card you would like to configure.
In the textbox next to SMS Number Plan you can create different number plans. Based on the following plan (in the submenu of CH1 = 1st SIM card), the 1st SIM card will send only those messages where the recipient's address starts with 01. Then the gateway will remove 01 from the beginning of the phone number.
The number plan of the 2nd SIM card accepts the messages where the recipient's phone number starts with 02. The gateway will also remove 02 from the beginning of the phone number.
