Faxes are received via the desktop Exchange client. CSID manages a database of all outgoing faxes and the LAN sender. It assumes incoming faxes from that some number will be for the original sender. OCR enables the fax server to read the fax and determine who the recipient is, it then forwards the fax to the appropriate folder or desktop. Both features have many configuration options and implementation levels.
Users send and receive facsimiles much the same way as e-mail.
The exchange server manages distribution and incoming faxes, they are then integrated for a user name or near match and placed in the users exchange inbox.
