But did you know you can also carry voice over Wi-Fi networks?  [Yealink's AX83H and AX86R Wi-Fi phones](https://www.teledynamics.com/catalog/keyword/yealink%20AX%20wi-fi%20phone) make a compelling case for this approach. Both deliver enterprise-grade voice capabilities and seamless mobility over Wi-Fi. In this article, we explore how Wi-Fi compares with DECT and Bluetooth for cordless telephony, then take a closer look at the AX83H and AX86R, comparing their features, capabilities, and ideal use cases to help you determine which is the better fit for your customers.

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.

For organizations looking to improve wireless capacity and performance without investing in 6 GHz infrastructure, [Grandstream's GWN7673](https://www.teledynamics.com/productdetails/GS-GWN7673) offers a compelling alternative. This enterprise-grade, dual-band access point delivers many of Wi-Fi 7's benefits while focusing on the 2.4 and 5 GHz bands that most businesses already rely on.

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.

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](https://www.teledynamics.com/productdetails/MEZ-BR-01) 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.

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.  [Read More](https://info.teledynamics.com/blog/securing-voip-communications-with-sip-over-tls-and-srtp) 0 Comments [Click here to read/write comments](https://info.teledynamics.com/blog/securing-voip-communications-with-sip-over-tls-and-srtp#comments-listing) Topics: [OTT VOIP](https://info.teledynamics.com/blog/topic/ott-voip), [VoIP](https://info.teledynamics.com/blog/topic/voip), [SIP](https://info.teledynamics.com/blog/topic/sip), [Network Security](https://info.teledynamics.com/blog/topic/network-security), [Unified Communications](https://info.teledynamics.com/blog/topic/unified-communications), [Communication](https://info.teledynamics.com/blog/topic/communication), [UCaaS](https://info.teledynamics.com/blog/topic/ucaas), [Protocols, codecs & standards](https://info.teledynamics.com/blog/topic/protocols-codecs-standards) [All posts](https://info.teledynamics.com/blog/all) [Next](https://info.teledynamics.com/blog/topic/unified-communications/page/2) ## Welcome to our Think Tank In this blog you'll read our thoughts on business telephone systems.
