  7. Software Design • Calendar Integration • Calendar data used to determine user availability • Program implements basic scheduler UI for user to make events and tag with specific status text • Also can import calendar data from common calendar programs • Parsed from standard xml format based on time periods with entries

  12. Software Design • Greeting Storage • Removeable SD or hard drive • WAV PCM • setmp3url() - Link application to greeting • VoicemailList – arraylist of greetings by ID • setVoiceMailGreetingid() • Voicemail Player • After Greeting is set • Login or Authentication • Voicemail object – defined by contact, time, etc.. • InputStream – recorded message • ByteArrayOutputStream • Raw audio, 16-bit
