You're going to be 20 minutes late for a final review sales meeting. Traffic is slow, but moving, so you don't want to risk sending a text message to your contact and get in an accident. You know she's in a meeting so you don't want to call her cell phone either. What do you do? Until a couple of years ago, you'd have to either call or dial the main number and leave a message with the receptionist. The recent emergence of voice SMS has provided a more palatable alternative. You simply record a message that you'll be late into your cell phone, and press send to deliver that message to your contact. She'll see that she has a message, and will press a button when she's ready to access it.
