Setup barix instreamer as MOH source

I’m wanting to setup an audio stream from a barix instreamer as a MOH source. I’m finding plenty of info on how to pick up an mp3 stream, I’ve done that before, with mixed results, mostly due to mpg123 dying for no good reason…

The barix unit is capable of encoding g.711u 8khz mono natively, to me, it seems it would be better to feed asterisk a native stream rather than have to run through mpg123 for transcoding. Has anyone else done this? I’m not coming up with much in my searches.
