You will have to use a third party fax server like RightFax to
accomplish this. With a product like RightFax you have the ability to
receive faxes on a single trunk line that has many different fax
numbers assigned to the same trunk (Direct Inward Dialing). When a fax
arrives on either of the numbers, the received fax can then
automatically be routed to any email adress or public folder. With a
product like SNAPSFLOW, you could have faxes come in on a single fax
number and then let SNAPSFLOW read certain information on the received
fax, such as a bar code. When the bar code is recognized, the fax will
then be routed to an individual, multiple individuals, a public folder
or even ftp'd to an entirely different location.
Hope this helps,
