Some of these tin-hat people I tell them to simply buy encrypted modems that do the encryption between the. Are there anyone out there selling good ones anymore?
Th issue is that there are two boxes connected via a modem and using PPP for IP traffic. The customer wants to be sure all traffic across that phone line is encrypted. Since they use so many network product some old those protocol may be plain-text. By having ppp encrypt what it sends that would cover any data that travels across.
