Voice mail is a pain, but it doesn't have to be. Just ask the million users who've now registered for YouMail, a 'digital secretary' type service that offers visual voice mail, smart filtering, voice-to-text transcriptions and custom greetings. YouMail, which operates only in the United States, says it has not only surpassed the 1 million registered users mark but has also handled over 300 million calls since its inception in 2007.
