[Tweet](https://twitter.com/share) [![](https://info.teledynamics.com/hubfs/blog-images/Bridge%20captioning%20device.jpg)](https://info.teledynamics.com/blog/make-workplace-calls-more-accessible-with-bridge-captioning) 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](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) ## [Work smarter with Yeastar's integrated communications ecosystem](https://info.teledynamics.com/blog/work-smarter-with-yeastar-integrated-communications-ecosystem) Posted by [Daniel Noworatzky](https://info.teledynamics.com/blog/author/daniel-noworatzky) on Apr 8, 2026, 10:08:00 AM - [Tweet](https://twitter.com/share) [![](https://info.teledynamics.com/hubfs/blog-images/yeastar-integrations(2).jpg)](https://info.teledynamics.com/blog/work-smarter-with-yeastar-integrated-communications-ecosystem) Every time employees switch between apps, re-enter information, or search across disconnected systems, productivity takes a hit.

You’ll often come across terms like “acoustic shield,” “active noise cancellation,” “AI noise cancellation,” and many others, all used to emphasize a device’s ability to deliver clear and intelligible audio. With so much marketing jargon, the actual meaning of these terms can easily get lost. In this article, we break down the terminology and explain what each of these features really means in practical, easy-to-understand terms.

Most people skim over these designations, preferring to focus only on the seemingly more important technical information. However, the truth is that these specifications are just as important as performance specs, protocol support, and device capabilities. In this article, we look deeper at these certifications, what each one means, the organizations that define them, and why they are important aspects to consider when choosing telecom equipment.
