One ISDN card is enough and fax@NET Plus receives and sends your faxes. You can send your faxes via the Web client, the fax@NET Plus Printer, or via a socket communication. Socket communication means that you can send faxes from any location in the world only over this interface. Many file types are supported. Sending a fax via the Web client is only possible with certain file types, but sending via the printer driver works with each application. You easily can send faxes directly from your Web site. A detailed log file makes it easy for administrators to find and solve a problem if something does not work properly.
