VoiceMail07. You're expecting a late night phone call from Hong Kong between 2-4am. You sleep from 8pm-2am, wake up for 2 hours, then go back to sleep from 4am-6am. Your phone is set on Voicemail during the hours you're sleeping. 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.
