Use native format audio (ulaw, alaw, gsm and the likes) not mp3.

[default]
mode=files
directory=/home/asterisk/wdeal-plateform/var/lib/asterisk/moh-native

With MP3 music-on-hold, Asterisk spawns only ONE mpg123 process (or
whatever you mp3player is). Thus, you have only ONE audio stream and all
your users hear the same music at the same time. It's recommended if you
have a huge number of users on hold at the same time.

With native format music-on-hold, Asterisk reads and streams the audio
as if it were a Playback. The music start at the beginning for EACH
user. So they DON'T hear the same sound at the same time. This method is
know to produce better quality sound than with mp3.
