Securing VoIP communications with SIP over TLS and SRTP

Posted by Daniel Noworatzky on Jul 1, 2026 10:01:01 AM

Voice and video communications carry some of an organization’s most sensitive conversations, but the systems that support them are often treated as ordinary network traffic, creating security gaps that attackers may be able to exploit.

Behind the scenes, signaling messages set up and control the session, while separate media streams carry the actual voice or video. If either of these components is left unprotected, attackers may be able to intercept call details, manipulate sessions, or capture media packets that were never meant to be exposed. 

That is why securing real-time communications requires attention to both parts of the call path. SIP over Transport Layer Security (TLS) helps protect the signaling messages used to establish and manage the session, while Secure RTP (SRTP) helps protect the media stream that carries the actual conversation. Together, these two technologies provide an important foundation for securing VoIP, UC, and other real-time collaboration services. 

In this article, we take a closer look at how SIP over Transport Layer Security (TLS) and Secure RTP (SRTP) work together to protect real-time communications. We’ll examine the difference between signaling and media traffic, what each technology helps secure, and why both are important for protecting VoIP, UC, and collaboration environments.

The UC super-app: why businesses want one platform for everything

Posted by Daniel Noworatzky on Apr 29, 2026 10:29:01 AM

When employees juggle six different apps to finish a task, technology is working against them. Most organizations didn’t set out to build a fragmented digital workplace; it just happened. A chat tool here, a video platform there, a ticketing system added during a growth phase, a file-sharing app bolted on during the pandemic. Each decision made sense at the time. But the cumulative result is a technology stack full of disconnected tools that create more friction than they eliminate.

The symptoms are familiar: employees bouncing between applications, losing context with every switch, suffering from notification overload and decision fatigue. IT teams wrestling with integration headaches, ballooning admin overhead, and an ever-growing security compliance surface. Taken together, it’s the predictable outcome of a fragmented stack left to evolve without a unifying strategy.

The good news? The solution isn’t a rip-and-replace overhaul. It’s a smarter center of gravity for your entire technology ecosystem.

That center is unified communications — and more specifically, the emerging concept of the UC super-app: a single interface that consolidates communications, collaboration, and business workflows into one cohesive digital environment.

In this article, we look at how the UC super-app trend is reshaping the enterprise technology landscape, why businesses are actively making the shift, and what a practical adoption path looks like.

Stop guessing: monitor the right VoIP and UC KPIs

Posted by Daniel Noworatzky on Mar 25, 2026 10:25:00 AM

Your network can be “up” and still deliver a terrible user experience. Dropped calls, choppy audio, and lagging video often go undetected by traditional monitoring tools until users start complaining. The key is knowing which performance indicators truly reflect real-time communication quality.

In this article, we break down the key performance indicators that matter most for VoIP and UC and how to use them to ensure a consistently high-quality experience.

How to fix cloud UC call quality with QoS, SBCs, and SD-WAN

Posted by Daniel Noworatzky on Feb 4, 2026 10:04:00 AM

 

Market trends continue to favor cloud-based UC deployments over traditional on-site call control, but users still demand PSTN-like availability, reliability, and service quality. What many organizations that move to the cloud quickly realize is that the move does not automatically guarantee better call quality—the usual culprits that cause both voice and video quality issues are still very much at play.

In this article, we explore the issues that lead to poor VoIP and UC communications quality in cloud-based deployments and how specific technologies and devices can be used to ensure consistently high-quality services.

Old rules, new networks: rethinking QoS for modern UC

Posted by Daniel Noworatzky on Jan 7, 2026 10:07:00 AM

UC is an area of telecom that has seen massive, rapid change in recent years. However, even given radical technological shifts, some principles remain the same. The need for quality of service (QoS) is one of them.

In this article, we take a fresh look at QoS from the vantage point of today’s UC, taking into account not only advances in QoS itself, but also in the underlying network infrastructure that serves it.

Boost UCaaS quality with smarter SD-WAN strategies

Posted by Daniel Noworatzky on Oct 1, 2025 12:17:40 PM

Hybrid and remote work have redefined the modern workplace. Teams now connect from headquarters, branch offices, home networks, coffee shops, and even while traveling — often switching between Wi-Fi, broadband, 5G, or satellite links in the process. With so many moving parts, keeping voice and video calls consistently clear can feel like an uphill battle. Dropped audio, frozen video, and lagging meetings are not only annoying, but they can be costly in terms of eroded productivity and hampered user experience.

This is where SD-WAN makes a difference. By intelligently orchestrating multiple types of connections, SD-WAN can turn this patchwork of networks into a reliable platform for communication. In this article, we’ll show you how SD-WAN helps overcome the pitfalls of underlay diversity, which mistakes to avoid when deploying it, and the best practices that ensure your UCaaS quality remains high. By the end of the article, you’ll be better equipped to assess your network strategy and support seamless collaboration no matter where your teams are working from.
