My only complaint about voice-mail is some callers leave inaudible messages...or they talk too fast to understand what was said.
Many of the later versions of voicemail systems I installed for business had a feature to let you either slow down or speed up the speed of voice of the person that left the voicemail without lowering or raising the frequency of their voice. In other words, not chipmunks or bullfrog sound, but several levels of faster or slower speech. Which is a pretty good trick if you think about it.
