The network configuration settings on the Barracuda Phone System are designed to be flexible in order to fit your existing network
infrastructure. This solution provides three common configuration types
in order to help you decide how to configure your server. This solution
assumes that the Barracuda Phone System is already physically
installed on your local network and that you have already logged onto the Web
UI and completed the First Run Wizard.
Using VLANs is a standard way to manage network capacity and security and, furthermore, is an effective way of improving call quality on networks which may suffer from congestion issues. The process of assigning a group of devices to their own VLAN is essentially a method of logically moving the traffic to a separate broadcast domain, the same as connecting them to a separate physical switch with separate network settings.
The Barracuda Phone System can be configured to work in this scenario by simply configuring the switch port to which it is connected as an access port in the VoIP VLAN. This will allow broadcast messages to flow to and from the phones in question. UI access to the Barracuda Phone System can then be configured by either:
- Adding a route for the data VLAN to reach the Barracuda Phone System in the voice VLAN -or-
- Configuring the Barracuda Phone System's WAN port to connect to the Data VLAN.
Different endpoint makes and models may have different level of support for VLANS and will very likely have differences in their supported VLAN features. Due to this, Barracuda recommends configuring VLANs on each phone per the manufacturer's guidelines, or using the phones in access mode and configuring VLANs at the switches/routers themselves.
