What is SD-WAN?

A software-defined wide-area network (SD-WAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections, which are used to connect enterprise networks – including branch offices and data centers – over large geographic distances.

Who is SD-WAN for?

The FoneLogix SD-WAN solution is built for organizations that need high-quality cloud-hosted voice capabilities. It helps companies make the best use of their available bandwidth for VoIP calls nationally and internationally. The solution offers benefits inside of the network and manages the data as it travels outside of the network to its destination. SD-WAN is especially beneficial for companies who have remote workers, several locations or branches, and workflows that require employees to rely on multiple network types or distributed networks. It also benefits organizations that have bandwidth limits and need reliability and stability for both VoIP and standard data.

What does SD-WAN do?

Our SD-WAN solution has two main functions:

  1. It optimizes voice traffic and reduces degradation of voice quality through the creation and transmission of duplicate packets over a specialized route. That specialized route is intended to reduce data packet loss for your network.
  2. It works to optimize your voice and data traffic within your organization and across the multiple networks you use. SD-WAN also monitors the usage of your bandwidth across both voice and data traffic and allocates bandwidth as necessary (based on policies and priorities that you can preselect) in order to ensure that you are getting the best quality and not wasting bandwidth.

Outside the Network, SD-WAN offers:

Voice Optimization

Your voice data gets prioritized and managed as it is sent to the provider. This process is an advantage to using our SD-WAN solution. Our SD-WAN solution automatically routes in the most optimal way possible rather than over standard internet routing, resulting in fewer lost packets and better voice quality on your calls.

Inside the Network,
SD-WAN offers:

Centralized Visibility & Management

SD-WAN gives your administrators the ability to view bandwidth usage and connections across all of your locations from a single screen. It offers information about where there are issues within your network and indicates if your ISP is having a problem rather than the hardware.


SD-WAN provides the ability to optimize the traffic of a distributed or hybrid network to improve utilization and stability.

Policy Enforcement

You can set policies on bandwidth usage and allocation that the SD-WAN box will enforce automatically, reshaping your bandwidth based on availability and policy. You can also prioritize locations or specific parts of your network, as needed.

Remote Orchestration

SD-WAN makes it easier to determine and provide a baseline level of access for all, whether your employees or guests are using managed devices, BYOD, or IoT and collaboration enablement devices.

Why should you be using it?

Aside from the drastic improvements to voice and data traffic, SD-WAN does some automated remediation for voice and network quality issues. SD-WAN optimizes voice and network quality whether you have a single location that uses a lot of bandwidth or multiple locations that use voice and data.
