Do voice email and audio postcard recipients need to have QuickVoice or Audio Postcard apps to play back voice mails?
No. Both QuickVoice emails and Audio Postcards are created in standard media formats. QuickVoice emails created on the Mac use QuickTime format and the Windows version uses WAV format. Audio Postcard for both the Mac and Windows use QuickTime format. The QuickTime players for Windows and Mac can be downloaded for free at www.quicktime.com.
