Secure Voice Communications While Travelling?

captnitro asks: "My father works for the US Dept of Commerce in the Eastern Bloc. His hotel room phones are routinely bugged -- a few (former) coworkers have had their stays 'shortened' and politely asked to leave the country, when they said dumb things over the phone. A few days ago he asked me what I use for secure voice when I don't have broadband. Remembering PGPfone from a while back, I looked up the link, but apparently they're no longer supporting/distributing it. While I wouldn't recommend he say much of anything in a bugged room, it got me thinking -- what do *you* use for simple, no-nonsense (requiring modem + sound card), low-bandwidth secure voice app? Unix works, and scriptability gets geek points, but I'll take what I can get."

asterisk or gnuphone by tzanger · 2003-09-19 14:29 · Score: 3, Interesting

You could use gnuphone with a SSH or other VPN tunnel, or even a full blown asterisk point and use encrypted IAX transfers. Any old SIP phone would work too.

All of these are IP solutions. Any decent pair of phone encoders (where you encrypt and decrypt the audio stream) would be a lower-tech solution that might work better.
