It may be obsolete technology but it is used by probably millions of businesses. Wes Leatherock snipped-for-privacy@aol.com snipped-for-privacy@yahoo.com
For reasons described elsewhere plenty of people still use fax.
One way of transmitting signed documents is creating a .pdf file and sending that.
There are many technologies that might be "obsolete" but still in use. What happens is that the usage simply goes down, but does not stop. Plenty of people still post transactions and do calculations using a No. 2 pencil, it's just a much smaller percentage of those doing so in the distant past. (Sometimes it's just easier to add up some numbers by hand than dig out a calculator or bring up a spreadsheet program.)
In some cases obsolete technology represents an investment and the equipment is still functioning. People with a perfectly good old television set aren't trashing them, they're using cable or a converter box. Many people have hard wired dial phones in their homes or business, they still work and don't hurt anything, so they're left in service. They're no longer a primary phone, but available for convenience.
Sometimes "obsolescence" is exaggerated by marketers or techies interested in pushing their product rather than true conditions. There were some who saw VOIP as making other phone lines totally obsolete, IMHO, they were jumping the gun.
