In today's digital age, businesses need a reliable and efficient communication network to stay competitive. With the rise of cloud-based services, such as Voice over Internet Protocol (VoIP) and Unified Communications (UC), traditional Wide Area Networks (WANs) may not be sufficient to handle the increased traffic and demand for high-quality communication services. This is where Software-Defined WAN (SD-WAN) comes in. In this blog, we'll explore the benefits of SD-WAN for VoIP and UC.

Benefits of SD-WAN for VoIP and UC

SD-WAN offers benefits for VoIP and Unified Communications (UC). We will be discussing some of the benefits here:

Enhanced Quality of Service (QoS): SD-WAN provides enhanced QoS for VoIP and UC traffic. It prioritizes traffic based on the application type, ensuring that real-time traffic, such as voice and video, are given higher priority over non-real-time traffic, such as email and web browsing. This ensures that VoIP and UC traffic is delivered with minimal latency, jitter, and packet loss, resulting in a better user experience.

Improved Network Reliability: SD-WAN uses multiple network paths, such as MPLS, broadband, and LTE, to create a resilient network infrastructure. It can automatically route traffic over the most optimal path based on the current network conditions, ensuring that VoIP and UC traffic is always delivered reliably. In the event of a network outage or congestion, SD-WAN can quickly switch traffic to an alternate path, ensuring that communication services are not interrupted.

Simplified Network Management: SD-WAN simplifies network management by providing centralized control and visibility. It allows IT teams to manage and configure network policies, QoS, and security from a single console. This simplifies the deployment of new sites, reduces operational costs, and ensures consistent policy enforcement across the entire network.

Cost Savings: SD-WAN can significantly reduce WAN costs by using broadband or LTE connections to augment or replace expensive MPLS links. It can also optimize bandwidth utilization by load balancing traffic across multiple paths, resulting in cost savings and improved network performance.

Increased Security: SD-WAN provides increased security for VoIP and UC traffic by encrypting traffic and providing end-to-end security. It can also provide micro-segmentation to isolate traffic and reduce the attack surface. This ensures that communication services are not compromised by security threats.


SD-WAN is an ideal solution for businesses that rely on VoIP and UC services. It provides enhanced QoS, improved network reliability, simplified network management, cost savings, and increased security. As more businesses embrace cloud-based communication services, SD-WAN is becoming an essential tool for delivering reliable and efficient communication services.

If you're looking to improve your business's communication network and enhance the quality of your VoIP and UC services, consider implementing SD-WAN. Contact us today to learn more about how SD-WAN can benefit your business.
