faxes:
„ FaxTransportMode = 1 (Relay)
„ V34ModemTransportType = 2 (Modem bypass)
„ V32ModemTransportType = 2
„ V23ModemTransportType = 2
„ V22ModemTransportType = 2
9.6.3.2 Using Relay mode for both T.30 and V.34 faxes
In this scenario, V.34 fax machines are forced to use their backward compatibility with T.30
faxes and operate in the slower T.30 mode.
Use the following parameters to use T.38 mode for both V.34 faxes and T.30 faxes:
„ FaxTransportMode = 1 (Relay)
„ V34ModemTransportType = 0 (Transparent)
„ V32ModemTransportType = 0
„ V23ModemTransportType = 0
„ V22ModemTransportType = 0
