In its simplest form, RightFax is a Windows 2000/2003-based fax server that emulates a print queue. When the server receives a document to fax, it calls one of four separate rendering engines: a PCL engine for jobs sent directly to the print queue using a standard PCL print driver, the optional Pscript engine for PostScript or PDF files, the INSO engine for documents received in their native application format (such as Microsoft Word or Excel files), or the Server-side application (SSA) conversion engine which uses locally installed applications to render files created in those applications. The server automatically decides which conversion engine to use based on the format of the submitted document and the installed conversion capabilities. After conversion to fax format, the server examines the destination fax number and compares it to a list of customizable dialing rules. Depending on the dialing rule matched, the fax is then transmitted via the local phone lines for transmission.
A comprehensive suite of optional add-on modules allows companies to customize each RightFax server for the unique needs of the fax users, workgroups and workload, whether to support specialized enterprise fax and e-document delivery, integrating with email and other third-party applications, or incorporating a wide array of powerful administrative utilities.
