I just happened upon the Internet Fax channel sponsored by RingCentral and thought it worth passing on if for no other reason than fax seems to keep on chugging along and has if anything been revitalized by the internet. It seems the market also received a great deal of adrenaline during the housing boom as massive stores of faxes were sent from buyers to sellers to mortgage companies, etc.
As a reminder, a channel on TMCnet is a microcommunity of interest designed to educate on a certain topic. We have built over 100 of these and I continue to be amazed at the traffic levels they generate.
If you have an interest in IP fax, be sure to check the site out when you get a chance.
