This feature allows Super Group 3 (SG3) fax machines to interoperate over T.38 fax-relay or Cisco
fax-relay networks. The capability to interoperate over fax-relay networks is achieved by enabling SG3
fax machines to negotiate down to G3 speeds by suppressing the SG3 V.8 fax call menu (CM) signal.
The suppression of the SG3 V.8 fax CM signal (or message) is also known as SG3 spoofing.
