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.

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.

Make workplace calls more accessible with Bridge captioning

Posted by Will Banta on Aug 19, 2026, 10:19:00 AM

For employees with hearing loss, phone calls can be one of the hardest parts of the workday. And with approximately 1 in 6 working-age adults experiencing some degree of hearing loss, the need may be more widespread than many employers realize.

Bridge was created to make workplace communication fully accessible for people with hearing loss. The compact hardware device connects to VoIP phones and computer softphones to deliver real-time captions for every call, helping employees participate on equal footing without changing how the rest of the team works.

But accessibility is only part of the story. In practice, Bridge is seeing the benefits extend further than expected. Captions can improve comprehension and retention even for people without hearing loss, and they can make it easier for employees to follow fast-moving conversations in a non-native language.

In other words, the Bridge captioning device can be a valuable accessibility tool while also bringing broader productivity and inclusion benefits to the workplace.

In this article, we take a closer look at this clever device and why it’s worth considering for virtually any unified communications or business telephony deployment, regardless of whether hearing accessibility is the primary need.

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.

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.
