[asterisk-users] Playing mp3-files – will it be OK?

[harry]

Hello

99% of all my users are calling from GSM phones, and my system
basically just plays some sound files back.

The PBX is connected to an ISDN-30 connection. Are there any modules
for playing MP3 files, so I can use them with commands like Play() and
Background()?

And will it have any effect on the quality?

Load issues should be a problem, the number of concurrent calls are pretty low.

Thanks
