I was using stock VM.
When someone would leave me a voice mail I would get a number ie. 1 on small voice mail icon on the home screen I would tap and there I was able to see who left it, time and play it from the phone.
Since 3 days ago when someone leaves me voice mail I would get text message saying
"xxx-xxx-xxxx has sent you a voice SMS message Call 408-970-0000 to listen"
I would call and it would be busy signal.
I called sprint and they didn't have any clue.
After searching the internet I came across this thread (thanks to RTan) and using
Option(2): it went back to normal.

Re-activate your Visual Voicemail account. This will force the Voicemail client to send an activation message to the Server again. Once re-activated, all pending messages should be able to download again.
EVO-Voicemails not going to Visual Voicemail, no notification of voicemail. - Android Forums
Option(1):
- Settings/Applications/Manage Applications/Voicemail/Clear data
- This will wipe out your old Inbox messages but your filesystem will come clean
Option(2):
Some suggested to use Visual Voicemail Compose screen and send it to the following address: activate@vvm.sprint.com
Good Luck. "
