VoiceMail06. There's a really good late night movie marathon showing (from: 9pm-5am), even though it's a school night. You set your phone to go to Voicemail because anybody calling you this late has no life. The "hour" parameter is the current hour time in the range 0-23. Add 12 to convert any PM hour to the 24-hour clock. Return true if your phone will go to Voicemail.
