I'm trying to set up my Google Voice mailbox over my phone. I don't have a microphone on my computer so I need to use my regular phone if I can. My problem is that I get a fast busy signal whenever I try to call my number and log in. I have the number set up for direct VM access, I just can't manage to reach it. Help, please.
You should read Google's help. You do NOT need a microphone to set it up, you tell it what phone to call to record the greeting.
