Configuring a 2N VoiceBlue Next GSM Gateway for 3CX Phone System

IMPORTANT: This guide is NOT a supported device. This guide is intended as a guideline only, and will NOT be updated.

This test was performed using Firmware Version 01.00.04f04 and Bootware Version 00.91. These steps may not work for earlier or later versions of the firmware.

Configuration is a 2 step process. First you need to configure 3CX Phone System for use with the GSM Gateway. Then, you need to configure the GSM Gateway to register and communicate with 3CX Phone System.

Step 1: Configuring 3CX PhoneSystem for the 2N VoiceBlue Next

  • In the 3CX Management Console, click on the “Add PSTN Gateway” button in the toolbar:
    • In the “Name” field, assign a name to this device; e.g. “2N VoiceBlue Next”.
    • In the “Brand” field, select “Generic”.
    • In the “Model” field, select “Gateway Device”.
    • Click the “Next >” button.
  • In the “VoIP Gateway Configuration” page:
    • Set the “Gateway Hostname or IP” field to the IP Address of the device (in this example 10.0.0.37).
    • Set the “Gateway Port” field to the port number of this device (default is 5060).
    • Set the “Number of ports” field to “1”.
    • Set the “Type” field to “Custom”.
    • Set the “Number of channels per port” field to “2”.
    • Click the “Next >” button.
  • The “Add VoIP Lines: Create Lines” page will appear and the necessary fields will be pre-populated with suggested values. You may customize these values for your requirements, even though the default values suggested should work well. Take a note of the Virtual Extension number, Authentication ID and Password. Click on the “Next >” button.
  • The “Create Outbound Rule” page will allow you to quickly create a rule with which to deliver calls through this device. Specify a prefix for the rule to identify outbound calls. Click on the “Finish” button when ready, or click on the “Skip” button if you do not wish to create an outbound rule for this device at this stage.
  • The “Gateway Created” summary page will list the settings you will require to apply to the device.
  • In the 3CX Management Console, click on the “PSTN Devices” node on the left-hand side, select your newly-created device, and click the “Edit Gateway” button.
  • Select the “Inbound Parameters” tab.
  • In the “Call Source Identification” section:
    • Set the “SIP Field” dropdown to “Contact : Host Part”.
    • Set the “Variable” dropdown to “GWHostPort gateway/provider host/port”.
    • Click the “Add/Update” button.
    • Click the “OK” Button at the bottom of the page.

Step 2: Configuring the 2N VoiceBlue Next

Configuring Basic Network Settings

  • Connect the LAN cable and insert the SIM Card before you power on the device. Ensure that any call barring, call forwarding and PIN codes are disabled from the SIM.
  • Connect the 2N VoiceBlue next GSM gateway to the network and mains power supply. The device will boot up, using its factory-configured default IP address 192.168.1.2.
  • Now point your browser to the gateway’s configuration site: http://192.168.1.2 . Your machine will need to have an IP address in the range 192.168.1.3 or similar to connect to the device.
  • Enter the username and password of the device and click “OK” to access the gateway’s configuration. The default username is “Admin” and the password is “2n”.
  • On the “Gateway Configuration” node click on the “Ethernet Configuration” subsection.

  • You should now set the desired IP address, subnet mask, Gateway and DNS settings for the device.
  • Click on the “Save” icon to commit the changes made.
  • Ensure you put your PC back to the correct IP range.

Configuring the settings for the GSM SIM Card

  • Point your browser to the gateway’s new IP.

  • On the “VoIP Parameters” node in the “SIP Protocol Settings” set the following fields:
    • Set “Use CLIP from INVITE field” to “FROM”.
    • Set “Send 180 Ringing instead of 183 Session progress” to enabled.
    • Enable the checkbox for “Sending DTMF according to RFC2833”.
  • Still on the “VOIP Parameters” node in the “SIP Registration” section set the following fields:
    • Set “Registration domain (realm)” to the IP address of the 3CX Server.
    • Set “Caller ID” to the Virtual extension number noted earlier.

    • Set “Password” to the Password noted earlier.

  • Still on the “VOIP Parameters” node in the “IP Addresses” section set the following fields:
    • In the “SIP Proxy (GSM->IP)” field enter the IP address of the 3CX server. The port should be set to “5060” for both unless your PBX uses a different port.
    • In the “SIP Registrar” field enter the IP address of the 3CX server. The port should be set to “5060” for both, unless your PBX uses a different port.
  • Click on the “Save” icon to commit the changes made.
