Re: Dial-in Fax to Email Server

The usual way of doing this is to have a group of DID numbers assigned
to one or more incoming lines.  For instance you could have
200 phone numbers assigned to one incoming phone line.
Then you assign a unique DID phone number
to each person/company that will be receiving incoming faxes.
When the calls arrive, the phone company sends info about which DID
number was called as part of the call connection process.  Your
hardware grabs this, then you know where to route the incoming FAX.

Not sure if any common pc modems can deal with the DID signaling
information.  You might need to use something like dialogic cards.

The other approach is to use an ISDN line for the incoming calls,
these often give you the "called number" as part of the call
setup.  For instance if you have a 3COM/USR Total control modem
rack connected to and ISDN PRI line, you can get this kind of
info on the incoming calls.  


For examples of people using these techniques look at the services
that provide fax to email services -- like www.jfax.com
