Telos releases Z/IP ONE v1.5.0r software

Telos releases Z/IP ONE v1.5.0r software 
New features, capabilities; free upgrade for Z/IP ONE users

29 June, 2012, Cleveland Ohio, USA

Telos has released a free-to-download software update for its popular Z/IP ONE IP codec, adding new features and capabilities at no charge to users.

"Our software engineers have been very busy," remarks Telos R&D engineer Jason Wisnieski. "We've improved our exclusive Agile Connection Technology for even better performance on 'iffy' IP connections. We beefed up Z/IP ONE's NAT traversal capabilities, which makes it even easier to connect to codecs behind firewalls."

"We've added new features too," Wisnieski continues. "We've added IPv6 support, automatic redial options, and tools for viewing and monitoring the status of WiFi connections. And we streamlined the front-panel menu so that the commands users need most frequently are even easier to get to. If you've already got a Z/IP ONE, you'll love this update; if you don't, now's a good time to get one!"

Z/IP ONE is a member of the Telos Zephyr family of codecs. It's a slim 1RU device that maximizes the audio quality of remote broadcasts over public IP networks and mobile phone data services ? even connections behind NATs and firewalls. Z/IP ONE codecs are EBU N/ACIP compliant with support for the SIP (Session Initiation Protocol) standard, which enables Z/IP ONE to connect to a variety of VoIP devices. Other features include the ability to connect to IP networks via EVDO, UMTS and Wi-Fi (each Z/IP ONE ships with a matched WiFi modem stick) and complimentary Telos Z/IP Server service that helps overcome troublesome firewalls and NATs, as well as easily find and connect to other Z/IP codecs.

Z/IP ONE gives broadcasters the largest choice of high-performance codecs available in an IP codec, including AAC-ELD, AAC-HE, AAC-LD, MPEG Layer 2, MPEG 4 AAC LC, MPEG 2 AAC LC, G.711, G.722 and linear PCM. Coupled with Telos exclusive Agile Connection Technology (ACT), these codecs enable Z/IP ONE to deliver exceptional performance on real-world networks, ensuring the best possible audio quality that public IP networks can provide.

Telos is the world leader for broadcast codecs, with over 20,000 Zephyr ISDN and IP codecs in use around the world. For more information about Z/IP ONE, visit For media information, contact Clark Novak at Telos Systems via email at, or call +1 216-241-7225.
