FAX Server and HylaFSP

The fax server is a piece of software running on the SOP. It is equivalent of having a physical fax machine. HylaFSP client connects to the fax server on the sop and transmits the documents. The fax server is then responsible to send them to the given external fax number.

The local fax extension is a dedicated extension used for sending faxes. You should have at least one, but its also common to have multiple local fax extensions, for example if you want one per person or one per department.

To proceed with the installation you will need to have the HylaFSP installer. But also a HylaFSP license is needed to use the fax client. For the configuration part you will need to have configured the ESCAUX FAX server.
