I had Google Voice for almost a month now. I was so excited to receive the Google Voice invite, as I had been wanting to get an account ever since GrandCentral days; the company and service that Google purchased and rebranded it into Google Voice.
For those who does not know, Google Voice is a service where Google assigns you an unique USA telephone number. Then whenever you receive a call at your Google Voice number, you can set up the service to ring any (US) telephone numbers you have. It also enables screening and grouping of these callers so that certain individuals can be directed to voice mail or a specific telephone number.
