I have successfully configured Trixbox 188.8.131.52 (Asterisk 1.4.22-3) such that people can call in to listen to a public lecture. They dial an extension, and then they are placed in the music on hold queue, which is actually playing audio that from the computer’s line-in port.
Everything works. The problem is that for people that have dialed-in, the music-on-hold audio quality begins to suffer, exhibiting a consistent “clipping” or choppiness, or stuttering. The Trixbox’s canned welcome message played to new callers is fine – no audio problems at all. But the MOH is clipping, and I can’t figure out what is causing it.
If I reboot the Trixbox, the problem goes away for a little while (no clipping). But after 10-60 minutes, it returns. I’m a total Asterisk/Trixbox noob, but it seems like potentially a buffering or interrupt issue. I’ve tried different codec settings to no avail.
Anyone have any ideas?
