Steve Church, FounderTelos was founded in 1984 by Steve Church, a radio station talk show host, who was dissatisfied with the poor quality of his on-air telephone calls. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a hit, eventually inspiring Steve to build a business to make and sell the systems.

Today, Telos telephone hybrids, talk show systems and streaming audio devices continue to set the performance benchmarks by which others are judged. Our Z/IP ONE IP codecs are the most advanced way to pass studio-quality audio over unreliable networks such as the Internet and mobile IP services. Livewire is an efficient, reliable way to transport, route, and distribute audio within broadcast facilities. VoIP systems for studio telephones complete the story.

Z/IP ONE IP CodecDespite having grown to become a worldwide leader in broadcast technology, we remain owned and managed by the founders. There are more than a dozen ex-broadcasters on staff making decisions, providing support, and designing products. Because we have "been there," we understand what you need to successfully get your job done. Since we are not beholden to finance types, we can take the long view, investing in fresh ideas for the long-term.

Broadcast Telephone Systems

VX Broadcast VoIP

VX is the world's first VoIP (Voice over IP) talkshow system - a SIP-based broadcast phone system so powerful it can run all of the on-air phones for your entire plant, but economical enough for stations with just two or three studios.


VX Prime Broadcast VoIP

VX Prime is the little brother to the full VX Broadcast Talkshow system, offering the same level of high performance to smaller facilities with two to four studios—all on an IP backbone that sounds better and costs less.


Hx6 Six-Line Talkshow System

Hx6 is the six-line, dual-hybrid broadcast phone system that makes your on-air phones sound great, at a price that's startlingly affordable. An Hx6 in your studio is like an instant audio upgrade for POTS or ISDN phone lines.


iQ6 Six-Line Telco Gateway

A multi-line phone system that connects to your console with just one cable? Meet iQ6, the no-hassle Telco gateway for Axia Audio mixing consoles. iQ6 plugs right into Livewire AoIP network networks, saving money and time.


Hx1 & Hx2 Digital Hybrids

Telos pioneered the very first digital adaptive telephone hybrid. These third-generation POTS hybrids have earned a worldwide reputation for extracting clean, clear caller audio from even the most difficult calls. POTS phones never sounded so good!


Audio Codecs & Transceivers

Z/IP ONE IP Broadcast Codec

Z/IP ONE, the award-winning IP codec from Telos, helps you get the best possible quality from public IP networks and mobile data services; even from connections behind NATs and firewalls. It's the IP codec that drops jaws -- not audio.


Zephyr iPort PLUS Multi-Codec Gateway

Zephyr iPort PLUS is a Livewire-to-MPEG/AAC/aptX gateway that transports multiple channels of stereo audio across any QoS-enabled IP network -- perfect for large-scale distribution of audio to single or multiple locations.


Zephyr Xstream ISDN Codec

Zephyr pioneered the concept of the ISDN codec -- which is why you'll find more Zephyrs in studios and remote kits around the world than any other codec.


Zephyr XPort POTS + ISDN Codec

With Zephyr Xport, you get ISDN audio quality with POTS economy. Xport is the world's only POTS codec that talks to the Zephyr Xstream ISDN codec. So you get the most reliable connections, and the best audio, too.
