Those tones are called CNG, or calling tones. If your faxmodem isn't
generating them on outbound calls, my snap reaction is: get a newer
modem. :-)
Seriously; almost every faxmodem built in the last 10 years has known
to send those automatically when originating calls in fax mode. It's
so automatic that I don't even know that there's a knob to adjust it.
In general, it really should only affect calls to fax switches, which
need the beeps to route calls to the fax machine. Most fax machines
shouldn't care, if they're on dedicated lines.
