Intelligent fax boards provide significant benefits over class 1, class 2, and fax/data modems.
Brooktrout SR140 series virtual fax boards are used only in IP telephony environments. SR140 virtual technology requires T.38 and either SIP or H.323 call control protocols. There is no form factor as SR140 is a virtual host-based fax board.
