Asterisk Mp3

I want to use MP3’s for hold music, and for fun, with Asterisk

Convert all mp3’s in a directory for use with asterisk.

#!/bin/bash
for f in `ls *.mp3` ; do FILE=$(basename $f .mp3) ; \
ffmpeg -i $FILE.mp3 -ar 8000 -ac 1 -ab 64 $FILE.wav -ar 8000 \
-ac 1 -ab 64 -f mulaw $FILE.pcm -map 0:0 -map 0:0 ; done

Asterisk Configuration

nano extensions.conf

; Answer required as Music On Hold does not answer the call
exten => 2112,1,Answer
exten => 2112,2,MusicOnHold(rush)

I used this to play 2112 whenever you dial extension 2112.
