[Asterisk-Users] Native MOH - Convert mp3 to ulaw

[Douglas Garstang]

I tried that earlier today... found it somewhere online... This is what I get...

[root at bil-pdev-5 mp3]# sox -V fpm-calm-river.mp3 -t au -r 8000 -U -b -c 1 fpm-calm-river.ulaw resample -ql                         
sox: resample opts: Kaiser window, cutoff 0.940000, beta 16.000000

sox: Failed reading fpm-calm-river.mp3: Do not understand format type: mp3
