I try to be ethical and only promote green products, so with that in mind I recommend Ring Central.  I'm trying to show people how you can still conduct business and still make money while helping the environment.  If you are not receiving everything paperless by now you are behind the times.  Don't waste your friggin' time shredding things either, nowadays cell phones are just as safe as fax lines.  So make the small effort to help our environment and check out Ring Central.
