[asterisk-users] sox: Failed reading obd-demo.mp3: Do not understand format type: mp3

[Sam Govind]

1- *-bash: obd-demo.ulaw: No such file or directory* // try use absolute
file path i.e /usr/src/mymp3.mp3 . I guess that's why its saying no such
file or directory.
2-  http://lists.digium.com/pipermail/asterisk-users/2006-March/144689.html Go
through this thread.
3-  When everything fails from sox - libraries dependencies issues  I use
http://www.nch.com.au/switch/index.html this converter. This can help you
for some time for free.
