Voice Fax Data Discrimination Software (VFD discrimination software)
Floreat Voice Fax Data Discrimination Software (VFD) is primarily required in telecom products, media gateway or VFD relay products to provide transparent service for various types of calls. The VFD discrimination software is used to detect and identify the call type as voice, fax, or data call so that the system can handle proper routing of the call to the appropriate function.
