Configuring Topex Mobilink GSM Gateway with 3CX

IMPORTANT: This device has been tested for Voice using Firmware Version Mobilink-IP-1.2.13-C2P-SDX

Setting up the Topex Mobilink IP

  1. Insert a SIM card into the Mobilink IP by opening the simtray by pressing the small yellow button with (for example) a pen. Insert the SIM card in the tray and slide the tray back in. Also, ensure both antennae are connected to the device.
  2. Start up the device and connect it to the network. The default IP address of the device is 192.168.173.1.  If your network uses a different subnet, please consult the Topex manual to see how to connect to this IP.
  3. Using a web browser, connect to https://192.168.173.1. If you get any security warnings or messages, proceed to the Topex device’s web console. When it opens, click on “Administration” in the left pane, which will prompt you to log in. Note that the default username is “admin” and the default password is “99admin11”.
  4. If you need to change the network settings to fit your subnet, select the “Network” > “IP Settings” option in the left pane and adjust as required. Click on the “Save” button, then click the “Commit” button on the left side and allow the device to reboot. When it loads, you can access the device on the new IP address.
  5. If you have a pin code on the SIM card, you need to set this.

Setting the PIN on the SIM card

    1. Select the “Mobile” > “Settings” option in the left pane and click the “Edit” link in the “Action” column.
    2. Now click on the “More” link.

      You can now insert the PIN of the SIM card in the PIN field.
    3. Click the “Save” button, followed by the “Commit” button.

      You can check the status of the mobile/SIM card connection by selecting the “Mobile” > “Status” option.
