Configuring Clipcomm CG410 for 3CX Phone System

Follow these steps to set up a Clipcomm CG-410 VoIP gateway for 3CX Phone System:

  1. Ensure that you have created the PSTN lines in 3CX Phone System first. Take note of the Authentication ID field and the Authentication password that you have entered for each line connected to the VOIP Gateway.
  2. Connect the Clipcomm CG-410 gateway to the network and mains power supply. The device will boot up, and providing you have DHCP installed on your network, will obtain an IP. To get the exact IP number, check the most recent DHCP lease, or alternatively use a network scanner to find a device with the string ‘Clipcomm’.
  3. Now point your browser to the gateway’s configuration site: ‘http://:1001’ where is the IP address leased by the DHCP server to the gateway. The “:1001” suffix is the URL’s port portion, indicating that the site is on port 1001. This is the factory default port on which the web interface is configured.
  4. Enter the user name and password of the device and click ‘OK’ to access the gateway’s configuration. The default username is admin, and the default password is 0000.

  5. Once the page loads click on the “System Configuration” link on the left hand side menu. The menu will expand. Click on the “VoIP” menu item to load up the System Configuration / VOIP page.
  6. In this page, configure the SIP server field with the IP or FQDN of the server on which 3CX Phone System is installed.
  7. Make sure “Server Registration” is “enabled”.
  8. In the “Registrar Server (FQDN)” field enter the name or IP of the 3CX Phone System Server. You can leave the outbound proxy field empty, since it is the same as the ‘Registrar Server’ – 3CX Phone System performs both functions.
  9. In the ‘Channel’ table, VOIP1 - 4 represent the 4 PSTN lines connected to the gateway. Configure each line as follows;
    a. The ‘User ID’ field should match the Internal Line Number field of the line created for this PSTN line in the 3CX Phone System Management console.
    b. In the ‘Display Name’ field, enter a name for the line.
    c. In the Authentication ID and Password fields, enter the ID and Password that you entered for the line in the 3CX Phone System Management console. These fields must match the ID and password set for that line in the 3CX Phone System Management Console.
    d. In the ‘RTP port’ field, enter the RTP Port which you want the gateway to use for the outbound connection. You can leave the default values.
  10. The “Register Expires (sec)” field sets the interval at which the gateway device will renew its line registration with the 3CX Phone System Server. You can leave the default value of 3600.
  11. Select the “Voice Codec” G 7.11 Mu law.
  12. Click on the “save” button to save your settings. The other settings that were not discussed are optional and can be left as default.
  13. Click on the “Supplementary Function” link under “System Configuration” on the left hand side menu column. The Supplementary function page will load.

  14. In the first table, with the headings VOIP1 – 4, select “1-Stage FXO Gateway” for each line. This will instruct the device to forward all outbound calls to the PSTN. The second option “2-Stage FXO Gateway” will require authentication using a PIN for each outbound call, and is not suitable for use with 3CX Phone System.
  15. In the second table, with the headings PSTN 1 – 4, you configure to which SIP extension inbound calls from the PSTN are routed. For each line, in the ‘Call forwarding field’ enter the line number of the PSTN line that you created in 3CX Phone System Management console. The Call forwarding number must match the line’s internal line number in the 3CX Management Console.
  16. Click save to save the settings and restart the device
  17. After the gateway has restarted, switch to the 3CX Phone System Management console, and click on Phone System > ‘Line Status’ (This is the default page). In the section ‘External Lines’, the PSTN lines connected to the VOIP Gateway should be listed with a green status light.
