I hate voicemail. It's usually a total waste of time and money as the message itself tends to be "call me back at the number you already have" so I usually disable voicemail as a feature. This actually means that incoming calls are not forwarded to your voicemail. Seems like a problem solved only until I got a smartphone that has voicemail button right next to call button:
