I've been trying to find out how to go back to using Verizon basic voicemail so I can call my VM and clear out the message I got while I was setting up GV. I tried using *71 + my number (the same way I changed to GV), but when I try to call my VM after that I get a busy signal. I had never set up the Verizon VM before, so I don't even know how to use it.
