Text Voicemail

I want an option to receive voicemails as text, and send voicemails as text. Sometimes I really want to know what someone wanted, but am not in a place where it's appropriate to listen to a message (I'm reminded of class, where it's still disrespectful but at least it's discreet). Similarly, sometimes I have something to tell someone who I know is at work but its too long to text (I don't have a full keyboard and cannot figure out T-9 for the life of me, so it takes a while...) I want to be able to have my voicemail translated into text for me.
