Yes, the standard sox in CentOS/RHEL is compiled without mp3 support.
When i invoke the same obd-demo.mp3 it works perfectly fine

Asterisk is nothing to do with your problem.
[root@host0040 ~]# rpm -qa | grep sox
sox-12.18.1-1.el5_5.1
[root@host0040 ~]# rpm -qa | grep lame
lame-3.98.4-1.el5.rf
lame-devel-3.98.4-1.el5.rf
[root@host0040 ~]#
Having lame and lame-devel is good; you will also need libmad and libmad-devel.
But the standard sox doesn't look for them.
MP3 support in SoX is optional
and requires access to either or both the external
libmad and libmp3lame libraries. To see if there is support for Mp3
run sox -h and
look for it under the list of supported file formats as
mp3.
[root@host0040 ~]# sox -h

Which package contains libmad and libmp3lame libraries available on CentOS 5.6
You will need to get libmad and libmad-devel from rpmforge, like you
did lame and lame-devel. There might even be a sox package on there
that was compiled with mp3 support. If not, you will need to obtain
the SRPM for sox and recompile it with mp3 support on your system.
That will probably involve editing the spec file to enable mp3.
Cheers
Tony
