The development of the SIP Opus Stereo Encoder/Decoder hardware and software was specifically made for iHeartRadio by Barix engineers. "Opus and SIP are the future of interoperability" says Steve George from iHeartRadio. To ensure multivendor operability it was decided to use the open, royalty-free Opus audio codec combined with the SIP protocol as a common handshake. "We like Barix because their boxes have been fairly bulletproof; they’re simple devices that generally perform one defined task, but do it very well. We had confidence that Barix devices would reliably do what they are supposed to do, and do it cost-efficiently." Barix went from concept to having hardware live in the field in just over three months. "An incredible turnaround time". This project will span multiple sites interconnecting 850+ radio stations.

Amtrak operators use traditional microphones to make their announcements, which are converted from analog audio to a digital stream by Annuncicom 100s. If the output device is available, the announcement is directly streamed to the output with a very small delay. If the output Annuncicom is already busy with another stream or previously recorded message, the Annuncicom 100 stores the message in real time into flash memory, and sends the message as soon as the output is available. “Barix was the perfect choice for this project because they were the only vendor that could so seamelessly implement modern, digital IP intercom technology into an existing analog paging system,” said Bryan Min, president and CEO of Epsilon Systems who implemented the system. “Barix was able to keep the product and integration costs to a minimum for Amtrak while also providing the customized programming that Amtrak required."
