Well, its an Austel requirement.

That risks a calling fax machine getting brain faded about the modem tones.

Strictly speaking, since a fax should be putting CNG tones out right thru
the dialing, the answering modem should see those as soon as it answers,
while its doing the Austel pause, and just notice its a fax anyway.
