One of those nagging things: music on hold sounded real slow in Asterisk. By default, asterisk uses mpg123. The small print of the documentation (and some web links) showed that the version default with the Debian on the test server is indeed not 'right' for this task. So, after rebuilding mpg123 from source I had working music on hold with a collection of irritating earworm music! Time to find a better source of music.. maybe Podshow has some feed I can use for podsafe hold music.
