I am elated that the development of Speak Freely is continuing. I think it

The versions of all the secure phones I've evaluated needed this feature: a minimal answering machine. With just the ability to record IPs of hosts that tried to call. (A local table can map these to your friends or their faces. Of course, this table should be encrypted when not in use.) Heck, you could even have an option to send email --or I suppose use that instant-messaging stuff that teenagers are fond of-- from the secure IP phone to you, when that phone rings but is not answered.
