I just activated Google voice in order to get a 2nd phone number for my cell phone. I selected 503 852 1662 because it was similar to my cell phone at 503 806 1662.
With this 2nd phone number I was able to add a 2nd business listing at www.superpages.com
Another benefit is that I can now receive text messages at my Google number then forward them by email.
When someone new phones my Google number I hear their name introduced and then I can decide to answer the call or let it go into voice mail. Cool features for Google Voice, so I recommend that you visit www.google.com/voice and get a Google number.
