Telos Systems—part of the Telos Alliance—was founded in 1985 by Steve Church, a talk show radio host and engineer who was dissatisfied with the poor quality of the on-air telephone calls on his shows. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a great success, inspiring Steve to build a business to make and sell the systems. Telos Systems has since become the industry leader in broadcast telephone systems and IP and ISDN codecs. The breakthrough Telos Zephyr audio codec, for example, is one of the most successful digital broadcast products in history, with more than 21,000 in use worldwide. Telos telephone hybrids and on-air talk show systems set the performance benchmark for the industry, and we continue to pioneer groundbreaking technology that pushes boundaries and gives broadcasters the telephony solutions they need for reliability, efficiency, and the best possible sound quality.
