Step 3 - How to Configure Basic System Settings

  • Last updated on

 Before configuring the IP address and network settings, complete Step 2 - How to Configure IP Address, network Settings, and Firewall.

Verify the computer and the Barracuda Phone System are connected to the same network, with the appropriate routing to allow a web browser to connect to the Barracuda Phone System IP address.

Initial Configuration

  1. In a web browser, enter the Barracuda Phone System IP address, for example, type
  2. Log in to the web interface using the credentials admin/admin.


Network Setup

The first time you log in to the web interface, initial installation screens display for you to complete.

You can edit these settings later using the CONFIGURATION menu in the web interface.

Complete the initial installation screens to set up the Barracuda Phone System in your environment. 

Installation – Network Setup Screen

Enter the relevant configuration details for your environment:

  • LAN Interface

    The Barracuda Phone System supports using non-RFC1918 (i.e., public) IP addresses in a private LAN address space, however this is not recommended.


    • IP Address, Subnet Mask, and Gateway – These settings are automatically filled in with the values entered in Step 1 - How to Set Up the Barracuda Phone System.
      Use LAN gateway as Default Gateway – Select this only if you are using the WAN port; see below for more information.  
    • Behind NAT Router – Select if your Barracuda Phone System is behind a NAT device, and then click Auto-Detect to attempt to discover the proper external IP address. If automatic discovery fails, manually enter the external IP address.
  • WAN Interface – The WAN interface is optional. If you have a WAN connection, for example a dedicated VoIP circuit from a carrier, you can connect it to the WAN port on the front of the Barracuda Phone System and fill in the associated details.

    • IP Address , Subnet Mask , and Gateway Enter these values; contact your carrier if you do not have these settings.

    • Behind NAT Router – Select if your WAN port is behind a NAT device, and then click Auto-Detect to attempt to discover the proper external IP address. If automatic discovery fails, enter the WAN port external IP address.

Only one interface can be used as the default gateway. If both the WAN and LAN ports are used, the Barracuda Phone System uses the WAN port as the default gateway. To use the LAN port as the default gateway, select Use LAN gateway as Default Gateway in the LAN Interface section.

  • Static Routes – If any destination network ranges should not be routed to the default gateway, you can add them using Add Static Route. Enter the IP address , Subnet mask , and Gateway for each static route.
  • Hostname – Enter a hostname to allow access to the Barracuda Phone System by name in addition to the IP address.
  • Domain  Enter a domain name to allow your SIP endpoints to access the Barracuda Phone System with a domain name in addition to an IP address. If you are unsure about using the domain parameter, leave it at its default value.

    Your local DNS server must be able to resolve the hostname or domain name to the proper IP address for clients that access the Barracuda Phone System.


  • DNS Servers  Specify your preferred domain name servers or leave the default server IP addresses.
  • Proxy Settings  If your Barracuda Phone System must access the web via an HTTP proxy, enter the value in this field. The Barracuda Phone System requires HTTP access on port 80 in order to download updates.

In the Upper Right corner, click Continue to save your settings.

Activate Barracuda Phone System

You must activate your Barracuda Phone System. Fill in the required fields and click Activate. A confirmation screen opens to display the terms of your subscription. If your Server is connected to the Internet, activation will proceed automatically. Otherwise, you will be given an Offline Activation Code to enter once the form is completed.

Update the Barracuda Phone System Firmware

Update your firmware to the latest version.

Read the release notes to learn about the latest features and fixes provided in the new firmware version.

Use the following steps to update the Barracuda Phone System firmware:

  1. Click Download if the installed version does not match the Latest General Release.
  2. Click Start Download. Downloading the firmware may take several minutes; do not turn off the appliance during this process.
  3. Click Install once the download is complete to update the firmware.

    Firmware Installation takes several minutes to complete. It is important not to turn off the appliance during the install. Your Barracuda Phone System will be offline while installing, so schedule the install to minimize business impact.

    Upon completion, the system automatically reboots which may cause your web interface to disconnect momentarily. This is normal and expected behavior, so there is no need to perform a manual reboot. A Status page displays the progress of the reboot. Once the reboot is complete, the login page displays. Log in to continue with the initial system configuration.


    To update the firmware later, go to Configuration > Updates.


System Settings

Update the common system settings.

You can also change these later by going to Configuration > System and Configuration > Phones.

  • Admin Password – Enter the current admin password (default: admin) and then choose a new admin password.
    This does not change the password for the Administrative Console, however the Console is only accessible via the keyboard, which you may disconnect at any time. 
  • Area Code – Enter the default area code to use when performing seven-digit dialing
  • Extension Block Setup – Your system ships with a default extension number range of 2000-2999. You can add and remove extension number ranges here. For example, if your extension numbers are three digits beginning with 100, add an extension number range from 100 to 199. Be sure that your extension number ranges can accommodate not only your physical telephone extensions but also your other features like groups, conferences, automated attendants, and queues. (You may add and remove extension number ranges at any time from the Configuration > Extension Blocks menu.)

Extension ranges should never include 411, 911 or other specially routed dial sequences.

  • Automatic Provisioning – Use automatic provisioning to easily add phones to your Barracuda Phone System. Before you enable automatic provisioning, verify that your Barracuda Phone System is not on the same network segment as an existing PBX system, otherwise it may re-provision the current system’s existing phones.
  • Notifications – You must supply an email address where your Barracuda Phone System can send system notifications. You may also customize the type and frequency of messages. Choose a normal warning level and interval to configure messages at or above that level to be batched and sent out at the specified interval. Additionally, you can specify an immediate warning level which triggers warning messages at or above that threshold to be sent immediately.

Validate and Complete Setup

Verify you settings to ensure a valid configuration.

  • If the settings are valid, click Complete Setup to continue to the administrative interface.
  • To change settings, use the menu on the left to return to any screen to correct the settings.

To access this mode in the future, log in using the admin credentials you set in the previous step. You can update configuration settings in the CONFIGURATION section of the web interface.
