All GV incoming calls are transcribed into text and emailed or text'd (or both) to you within seconds. Many times I don't accept my GV on my cell phone when driving but I can read all my phone traffic at the next stop. This feature alone is so powerful I wouldn't go with a another service that didn't feature it. From a business standpoint it's almost priceless. You have a printed record of every phone message every customer has ever left you. That's pretty incredible really.
