Fax Voip Windows Fax Service Provider (FSP)

Fax Voip Windows Fax Service Provider (FSP) integrates virtual fax devices into the fax service. Microsoft Fax and Windows Fax and Scan, which are built right into Windows, are used to send and receive T.38 and audio (over G.711 codec) faxes using your VoIP (SIP or H.323).

Fax Voip FSP replaces the standard Microsoft Modem Device Provider by the Fax Voip T.38/G.711FAX Device Provider. This allows you to use the Windows Fax Service most efficiently. In particular, the ECM (Error Correction Mode) is supported. The busy signal is also detected correct way. Using Fax Service Provider (FSP) instead of Virtual COM Ports and modems significantly improves reliability of your fax system.
