The Wolf Creek Radio Case Study: Radio, Asterisk and Sangoma

Wolf Creek Radio teamed Asterisk and Sangoma to create a phone system that transitioned from off- to perfect on-air quality.

The Wolf Creek Broadcasting Network owns a group of three AM radio stations in North Georgia and Tennessee. With forward thinking owners, Wolf Creek empowers its IT department to implement the new technologies, as it sees fit, such as state-of-the-art automation software and streaming show content over the Internet.

A couple of years ago, it was not difficult to convince them to implement VoIP phone system. They chose Asterisk@Home-now Trixbox to inter-connect the stations over the Internet and completely eliminated inter-station long distance calls. This phone system worked well for inter-office calls. But the analog lines to the studio boards had to be left out of the new system. (At the time, Wolf Creek was not yet using Sangoma hardware.)

"I was never able to get the audio perfect enough to put on the air", said John Mullinix, the IT Engineer for Wolf Creek Broadcasting Network.

In spring of 2007, Wolf Creek won an FM frequency in the frequency auction. It needed to move to a new studio and corporate office.

Wolf Creek built state-of-the-art studios with a lot of equipment from Harris Broadcasting. This required a new, larger capacity, analog TDM card for its phone server.

Having used an echo canceling Sangoma A200 card in another installation, Mullinix decided to order and install a Sangoma A200 8-FXO, 4-FXS echo canceling card. "It sounded great", he said. "Good enough that I was going to put this card on the air".
