1. Is there an *.mp3 file located in /var/lib/asterisk/mohmp3 ?

2. If you do a ps -ax, do you see:
 3330 pts/0    S      0:00 mpg123 -q -s --mono -r 8000 -b 2048 -f 4096 xxx.mp3
 3332 pts/0    S      0:00 mpg123 -q -s --mono -r 8000 -b 2048 -f 4096 xxx.mp3
where xxx.mp3 is something in the directory noted above?

3. After you have a sip call established and you place it on hold, do
you see something like the following on the CLI?
    -- Called 3000
    -- SIP/3000-5a91 is ringing
    -- SIP/3000-5a91 answered SIP/3031-9ad1
    -- Attempting native bridge of SIP/3031-9ad1 and SIP/3000-5a91
    -- Started music on hold, class 'default', on SIP/3031-9ad1

4. Which distro are you using?
