The Generic SoftK56 Data Fax Voice Speakerphone Modem is a software-based modem driver designed to provide connectivity for K56flex modems, which were commonly used in the late 1990s and early 2000s for dial-up internet connections, faxing, and voice services. These modems are often referred to as "soft modems" because they rely on software (rather than hardware) to perform many of their functions. The "Speakerphone" feature allows voice communication through the modem, enabling services such as voice calls and answering machines.

This driver is typically used for K56 Data Fax Voice modems that are compatible with Windows and help manage the connection to dial-up networks, fax services, and voice capabilities.
