VoIP: Stop "them" Listening to Your Calls

Privacy Guru Locks Down VoIP
Story Text:

Wired reports that Phil Zimmermann, creator of Pretty Good Privacy e-mail encryption program, is bringing out a new system to protect VOiP calls. He will apparently announce it at the "BlackHat security conference in Las Vegas" tomorrow (I seem to have missed out on an invite to that one). Phil likens the internet to a "crime ridden slum", so he knows what he is talking about.

"Years ago, people kind of stumbled into e-mail without really thinking about security," Zimmermann says. "I think that what's happening today with VoIP is that we’re kind of stumbling into it (as well) without thinking about security." People don't think about it, he said, because they're used to phone calls being secure on the regular phone system -- known as the Public Switched Telephone Network.

"The PSTN is like a well-manicured neighborhood, (while) the internet is like a crime-ridden slum," Zimmermann says. "To move all of our phone calls from the PSTN to the internet seems foolish without protecting it."

Apparently you can listen in to others on VOiP with a free program called VOMIT

The program is called Voice Over Misconfigured Internet Telephones, a name clearly chosen for its catchy acronym -- VOMIT.
