But we get this message all the time though on normal voice calls and it's not because we're calling fax machines or modems.
The tone is put in by long-distance voice network echo cancellers -- calls over 400 miles IIRC. This prevents multiple ECs from trying to echo-cancel the conversations.
So it's not just a fax/modem tone. It's a Bell-standard telephone-network EC tone.
