Hi I have to play mp3 file in dialplan…

1. Can I directly play mp3 in asterisk?
2. Do I need to convert into .wav
3. If need to convert into .wav then can I convert in dial-plan only through below command

sox foo-in.wav -r 8000 -c 1 -s -w foo-out.wav resample -ql

You can convert the mp3 into wav using an AGI, then use the .wav in your dialplan  
Start your agi by using

> #!/bin/bash

So you can execute bash scripts

The sox version you have cant handle mp3 file, so you need to recopile sox with mp3 support or you might use lame, anyaway those packages are not asterisk related you can get help on their respective forums
