Silent Circle appears to be for people who both

1) Want military-grade(ish) hardened coms

and also

2) Aren't willing to set it up themselves, but trust a service provider to do it for them

I read their docs a bit ago and don't really get it. I didn't really get Whisper Systems offering either as it appeared to have a broken trust model on a variety of levels.

If I cared about this kind of thing, and I really don't, I'd likely want to own all parts of the transport system and have the only available threat surface be the encryption algorithm as much as possible http://www.voip-info.org/wiki/view/Asterisk+encryption

Might it all be pointless without massive amounts of traffic padding based on this attack? I wouldn't know. http://link.springer.com/article/10.1007%2Fs10207-010-0111-4...
