How do you troubleshoot an IP phone that won’t register? And how can you tell whether the endpoint itself is defective? Understanding how DHCP and LLDP-MED support provisioning can help IT teams streamline rollouts, apply settings consistently, and pinpoint the source of registration problems. 

An IP phone may look ready to use as soon as it is connected, but before it can place a call, it must learn where it belongs on the network, how its traffic should be prioritized, and where to retrieve its configuration. Thankfully, this initial setup, known as provisioning, can be largely automated.

Network protocols like the Dynamic Host Configuration Protocol (DHCP) and the Link Layer Discovery Protocol - Media Endpoint Discovery (LLDP-MED) help turn UC and VoIP endpoint deployments into a simple, highly automated, plug-and-provision process.

In this article, we explain how these protocols work and how they can significantly streamline endpoint deployment and ongoing management. 

By the way, TeleDynamics customers can take this automation a step further with our provisioning services. We can preconfigure IP phones before shipment so they arrive ready to connect and deploy at the end user’s location. 

Hybrid work has made headset flexibility more important than ever. Professionals no longer spend the entire workday in one place, connected to one device, using one communications platform. They may start the day on a desk phone, move to a laptop-based video call, take a mobile call, and later join a meeting from a shared workspace or home office.

That is where the Yealink WH68 headsets stand out. While many wireless business headsets support multiple devices, the WH68 series goes a step further by combining DECT and Bluetooth in a more flexible way. Its key difference is that Bluetooth is built directly into the headset itself, allowing users to connect through DECT at the desk or through a dongle, then use Bluetooth directly from the headset when they move away from that setup.

In this article, we examine the Yealink WH68 series and explain what makes its DECT and Bluetooth architecture different from many competing wireless headsets. We also look at its audio features, comfort-focused design, key specifications, and the three available variants: the standard WH68, the WH68 Hybrid, and the WH68 Workstation.

Cloud communications is a growing opportunity for resellers, MSPs, ITSPs, and service providers—but building a UCaaS platform from the ground up is a major undertaking. It takes infrastructure, development resources, ongoing maintenance, and the ability to support customers at scale.

White-label UCaaS gives providers a faster path to market. Instead of building the entire platform themselves, they can deliver a complete cloud communications solution under their own brand while relying on proven technology behind the scenes.

In this article, we look at what white-label UCaaS means, the business benefits it offers, and how Yeastar helps providers expand their cloud communications offerings with confidence.

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. 

As voice, video, collaboration, and professional AV traffic increasingly share the same network infrastructure, organizations need switches that can deliver more than basic connectivity. They need reliable performance at the access layer, simplified traffic prioritization, and enough flexibility to support not only everyday business networking, but also more demanding AV-over-IP deployments.

Grandstream’s GWN7800 Pro series managed network switches are designed for exactly that kind of environment. With a new professional AV feature set and three additional models, the series now addresses an even wider range of SMB, collaboration, and AV deployment scenarios.

In this article, we take a closer look at the GWN7800 Pro series Pro AV features, explore the latest additions to the lineup, and examine the types of use cases where these switches are especially well suited. 

While most network equipment is easy to replace, cabling is not.

Switches, routers, access points, and IP phones can be upgraded as technology changes. But copper cabling is often installed behind walls, above ceilings, inside conduits, and across patch panels, where it may remain in place for decades. That makes the choice of cabling category more than a technical detail. It is an infrastructure decision that can affect performance, reliability, upgrade paths, and long-term cost.

In this article, we take a closer look at what copper cabling categories mean, how they affect network performance, and how installers, resellers, and consumers can choose the right cabling for their needs.

Unified communications (UC) and professional audiovisual (AV) systems have historically been two distinct and separate disciplines with little overlap. Over the past decade, however, the barrier between these two has steadily been crumbling. UC and AV are rapidly converging, and AV systems are increasingly relying on IP networks.

This convergence has led to the introduction of new networking requirements and design approaches, such as AVLANs and AVIoT, which involve exciting new capabilities as well as design challenges.

In this article, we delve deeper into this convergence story, helping you to better understand the benefits and intricacies this evolution represents for both network engineers and AV integrators.

Focus rooms have become essential collaboration spaces for small teams, quick project discussions, and hybrid meetings that require more privacy than an open office can provide. But outfitting these compact rooms can be tricky: the technology needs to be powerful enough for professional video conferencing, yet simple enough to deploy without overbuilding the space.

That is the gap the Yealink MeetingBar A25 is designed to fill. With a compact all-in-one form factor, a triple-camera system, AI-enhanced video features, strong built-in audio, and support for both Microsoft Teams and Zoom, the A25 brings enterprise-grade meeting capabilities to focus rooms and huddle spaces.

In this article, we evaluate this intriguing new device, review its capabilities, and see how it fits in with the rest of the MeetingBar products that Yealink offers.

As traditional copper-based phone service (also known as the PSTN or POTS) is phased out across the country, tens of thousands of emergency communications devices are at risk of losing their lifeline. Elevator phones, fire alarm panels, burglar alarm systems, gate entry intercoms, and other life-safety devices were built to run on analog lines. And those lines are going away.

For telecom and UC installers and resellers, this situation is both a challenge and a significant opportunity. Vola Networks, a U.S.-based high-quality equipment provider, offers POTS (an acronym for plain old telephone service) replacement solutions tailored specifically for managed service providers (MSPs).

Having reliable wireless and wired network connectivity at small office branch sites and remote worker locations is of vital importance in today’s flexible and ever-changing work environment. Deploying the right wireless-enabled router can make all the difference in achieving that goal.

In this article, we explore the Wi-Fi 6 certified GWN7062M router, the newest model in the GWN7062 series of wireless routers offered by Grandstream. It introduces new capabilities to an already strong lineup, striking a balance among performance, security, and ease of deployment.
