I'm sure there are. Google is your friend. :)

You misunderstand. I was referring to voicemail *notification*. As in, the voicemail icon on your phone? In CDMA, a flag is set on your handset via the paging channel. On T-Mobile and older generation GSM networks, the flag is not sent (though that is starting to change on T-Mobile, slowly). Instead, you get an explicit SMS message that reads something like "you have 1 unread voice mail message."
