A fax machine uses a modem of sorts, just with one specific protocol and purpose. I can't find anything about how WarVOX differentiates modems from fax machine

A fax machine uses a modem of sorts, just with one specific protocol and purpose.
I can't find anything about how WarVOX differentiates modems from fax machines, but I wouldn't write them off right away.
- hdmoore 5y agoIt is based on peak frequency, you can visually see it here: https://speakerdeck.com/hdm/derbycon-2011-acoustic-intrusions?slide=24 https://speakerdeck.com/hdm/derbycon-2011-acoustic-intrusion... IIRC (it has been a bit), there was a specific frequency only used by modem negotiation but not fax machines (3150?).
