[Asterisk-Users] System cmd usage

[Bill Michaelson]

Using John Todd's example for recording, from his cleanup/conversion macro...

; Turn the two in/out .wav files into a single .wav file with both channels
exten => s,3,System(/usr/local/bin/wmix ${MONITORDIR}/${CALLFILENAME}-in.wav ${\
MONITORDIR}/${CALLFILENAME}-out.wav > ${MONITORDIR}/${CALLFILENAME})
;
; Remove the old .wav files - we don't need them anymore.
exten => s,4,System(/bin/rm ${MONITORDIR}/${CALLFILENAME}-in.wav ${MONITORDIR}/\
${CALLFILENAME}-out.wav)
;
; This part of the routine compresses the .wav files into a .gsm file for
;  better storage (about 1/5 the size of a .wav file).  Use "untoast" to restor\
e
;  to normal wav file format. (toast and untoast are fairly standard on Linux s\
ystems)
;
exten => s,5,System(/usr/bin/toast -F ${MONITORDIR}/${CALLFILENAME})

The wmix runs successfully (it produces the mixed file), and running "by hand" from the shell indicates that it returns 0 to the shell.  But the * console log seems to think it failed...

Any ideas why?
