SD-WAN and UCaaS

SD-WAN and UCaaS:  Better Together 

SD-WAN and UCaaS truly are better together.  We’ll outline unified communications and SD-WAN technologies and detail the benefits of using them together.  Learn more by contacting Brightlio today.

Why Should You Use SD-WAN for UCaaS Deployments?

Unified Communications as a Service (UCaaS) solutions are revolutionizing the way we communicate.   Unified Communications tools integrate voice, video, secure chat, file sharing, and contact centers into a single platform, making it easier to collaborate and communicate.  UCaaS technology also extends corporate telephony features and security policies to mobile devices, desktops, and laptops for remote users. 

Real-time voice and video communications are extremely sensitive to latency, jitter, and packet loss, which degrade voice and video quality.  These issues are especially prevalent where users are dispersed in many locations with varying types and speeds of network connectivity.  Proper provisioning of bandwidth is critical to the success of unified communications solutions.  This is where SD-WAN comes in.

SD-WAN (or software-defined WAN) is a software-based networking technology that uses virtual WAN architecture to connect users to applications securely.  SD-WAN aggregates broadband, DIA, LTE, and MPLS services to create multiple secure paths for data to flow.  It identifies traffic by application and routes the traffic appropriately for the best Quality of Service (QoS) and Quality of Experience (QoEx).  This allows us to build alternatives to traditional MPLS networks that are more cost-effective and flexible.

The Benefits of SD-WAN for UCaaS

There are many reasons why SD-WAN and UCaaS are better together.  Here are a few of the most compelling:

Better Voice and Video Quality

SD-WAN prioritizes voice and video quality, ensuring these latency-sensitive applications have the capacity they need and are routed appropriately for superior Quality of Experience. 

Improved Reliability

SD-WAN can bond multiple links together to enable an active/active topology.  This allows your UCaaS application to stay up in the event of a link failure.  Also, SD-WAN solutions can automatically reroute traffic around problem areas, leading to improved uptime. 

Cost Savings

SD-WAN is typically cheaper to deploy than traditional MPLS networks.  The savings can be meaningful, especially with companies with unified communications users in many locations.  Additionally, SD-WAN allows users to leverage lower-cost broadband connections or combine a dedicated internet circuit with a broadband connection, saving costs. 

Improved Security

SD-WAN allows you to segment your voice and video traffic keeping your UCaaS application safer from cyber-attacks.  SD-WAN features are frequently included with a firewall, providing SD-WAN plus a next-generation firewall for the cost of the firewall.

Fortinet is an example of a provider that combines the technologies in a hardware model.  Cato Networks is an example of a provider that offers a software-as-a-service approach combining SD-WAN and security with SASE, SSE, ZTNA, and other technologies. 


SD-WAN helps organizations meet compliance requirements like PCI, GDPR, and HIPAA through improved security and redundancy. Many SD-WAN solution providers offer architectural guides that walk you through how to deploy their solution against a specific compliance framework. This helps simplify compliance with an SD-WAN deployment.

Better Monitoring

SD-WAN solutions provide better monitoring options for unified communications and other applications.  These allow administrators to see trouble spots and adjust in real-time. 


Sometimes administrators don’t need to make adjustments because SD-WAN adjusts for them.  SD-WAN solutions can respond in real-time to network changes that could impact unified communications performance without intervention from the IT team. This leads to an immediate resolution to issues like congestion, link failure, or degradation of network traffic. 

How to Purchase SD-WAN and UCaaS

Purchase SD-WAN and UCaaS solutions together or separately. The choice is yours.  Some UCaaS providers, like Vonage, offer their own SD-WAN service.  This can be purchased with the unified communications suite for an integrated solution. 

Other UCaaS providers, like RingCentral, prefer to partner with industry leaders in the SD-WAN space, like VMware and Fortinet.  The team at Brightlio can help you to identify which solution package is suitable for your needs.
