Green communications: how to reduce UC and VoIP energy costs

Posted by Daniel Noworatzky on Oct 28, 2026, 10:28:01 AM

Green unified communications is about more than reducing the environmental impact of large data centers. Enterprise UC and VoIP systems also consume energy around the clock, creating opportunities for organizations to reduce both their carbon footprints and operating costs.

From always-on IP phones and PoE switches to UC servers, IP PBXs, and conferencing systems, enterprise communications infrastructure can represent a significant source of energy consumption. Fortunately, improving energy efficiency doesn't necessarily require major infrastructure investments. Smarter power management, optimized configurations, and more efficient equipment can deliver meaningful savings, particularly in large deployments.

In this article, we explore practical ways to make UC and VoIP systems greener and more cost-efficient, from individual endpoints to on-premises infrastructure and cloud-based communications services.

Yeastar AI: from employee assistance to smart customer interactions

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

For many businesses and their customers, the most familiar application of AI in communications systems has been the standalone chatbot. Yeastar has significantly exceeded that standard by incorporating AI directly into its P-Series ecosystem, working with actual calls, voicemails, call routing, and business workflows.

In this article, we showcase some of Yeastar’s most innovative AI integrations in two particular areas: AI that assists employees and agents, and AI that interacts directly with customers. As you will see, these aren’t just AI features for AI’s sake. Their purpose is to reduce repetitive work and make communication more effective.

UC and VoIP auto-provisioning: common pitfalls to avoid

Posted by Daniel Noworatzky on Sep 30, 2026, 10:30:00 AM

While automated provisioning has made bringing UC and VoIP endpoints online faster and easier than ever, even highly automated systems can run into trouble when common provisioning pitfalls are overlooked. Knowing where those problems can occur and how to avoid them can mean the difference between a smooth rollout and a frustrating troubleshooting exercise.

Behind the apparent simplicity of today’s provisioning systems lies a chain of network services, protocols, security mechanisms, and configuration dependencies that must all work together correctly. A problem at any point in that chain can prevent a device from provisioning or registering as expected.

In this article, we walk through the UC and VoIP provisioning process, highlighting common points of failure that even seasoned professionals may encounter and what to look for when things don’t go as planned.

Stop selling UC like a product: 7 mistakes to avoid

Posted by Daniel Noworatzky on Sep 23, 2026, 10:23:01 AM

Unified communications (UC) has come a long way from the days of traditional PBXs, voice trunks, and analog phones. Since communications technology has changed so dramatically over the years, shouldn’t the way we sell these solutions evolve as well?

Many resellers still approach UC as if they are selling boxes, devices, and standalone services, but today, UC is much more than that. It is a communications solution that becomes part of an organization’s workflow, business processes, customer experience, and overall operating model.

In this article, we explore seven mistakes that resellers make when selling UC solutions, along with practical ways to avoid them. Although this is a list of “mistakes,” it really outlines best practices for selling UC solutions. The overarching principle is that the most successful resellers are not just moving boxes or quoting licenses. They are trusted advisors who help customers understand what they actually need.

Connect buildings without new cabling with the Grandstream GWN7302

Posted by Daniel Noworatzky on Sep 16, 2026, 10:16:00 AM

Sometimes the hardest part of extending a network is simply getting from one building to the next. Running fiber may be expensive, disruptive, or impractical, while adding separate Internet connections introduces recurring costs. The Grandstream GWN7302 wireless bridging device offers another option: a high-speed wireless bridge that can link buildings and facilities over distances of up to 3.1 miles (5 km). 

This device is especially useful for linking buildings and facilities on a campus, allowing them to communicate and share network services such as internet connectivity. In this article, we review this Grandstream device, share its advanced features, and explore the most common use cases for which it is best suited.

Build a flexible DECT system with the Yealink W70B

Posted by Daniel Noworatzky on Sep 9, 2026, 10:09:00 AM

One of the biggest advantages of the Yealink W70B base station is the flexibility to build a cordless communications system around the way a business actually works. 

Rather than supporting just a handful of cordless handsets, the W70B can serve as the hub for a broad mix of Yealink DECT endpoints, including handsets, headsets, desk phones, a conference phone, and range-extending repeaters.

That versatility makes it possible to support very different users and work environments from a single DECT platform, whether employees are moving through a warehouse, working at a desk, joining an impromptu conference, or operating in a rugged environment.

In this article, we take a closer look at the W70B and the compatible DECT devices that make it such a flexible foundation for business cordless communications.
