Voicemail is saved in multiple formats and then played back using the format that most closely matches the endpoint.
So if you call using ulaw you should be hearing the file that is saved as an uncompressed .wav. If you disable the other formats it will do the conversion on the fly if needed. The default Asterisk sound files are all GSM and thats why people complain they sound bad. Since you specifically mentioned digits I suspect this may be what your user is noticing. There are new sound files for Asterisk 1.4 all done in uncompressed .wav.
