You don't want to do this.

Asterisk will attempt to use prompts encoded with the same codec being 
used for the channel. So, unless you have a channel that is using MP3, 
Asterisk would have to transcode the prompt every time it is used. Why 
would you want to "burn" CPU cycles for this useless activity?

You should strive to have prompts available in all the channel encodings 
actually used by your system. I have systems that only use ULAW, so all of 
my prompts are encoded as ULAW. (Sometimes I "cheat" and use WAV files 
since they are easier to work with and transcoding from WAV to ULAW is 
"cheap.")
