What Hacker News says

14 sources
according to this it does https://github.com/WhisperSystems/RedPhone/issues/143 However, like the majority of network-enabled Android applications, RedPhone relies on the existence of APIs provided by the Play Services Framework. If you're avoiding Google Play because you don't want your device to "phone home," you should be aware that merely having Play installed (even without an account registered) is enough for your device to phone home. If you uninstall Play, however, the Play Services Framework will be unavailable, and RedPhone (along with many other applications) will not function.
In TextSecure: Forward secrecy for asynchronous messages
silent circle is closed source and everything goes through their server. Sure they can claim not to store much logs, but when some government entity puts some secret orders on them, who knows what will happen. Remember that having the metadata, who calls who, is already a big win for surveillance entities. RedPhone is owned by twitter, same story, but the client is open source, and maybe they have plans to release the server too, but you would have to compile your clients too since apparently the servers are hardcoded into the client. Both of these are thus not federated. Ostel is open source client and server side, you can easily set up your own server, and if I understand it correctly it's also federated. Some reading: https://github.com/WhisperSystems/RedPhone/issues/63 https://guardianproject.info/2012/07/05/a-network-analysis-o...
In Ostel: Encrypted Phone Calls
> I'm thinking some ways of encrypted mobile-to-mobile communication, file storage, maybe even encrypted video. There's a few good open source implementations out there already for phone calls and SMS. The two below were done by Moxie Marlinspike. They're built for Android, but I'm sure they can be ported elsewhere with the source being available. https://github.com/WhisperSystems/RedPhone https://github.com/WhisperSystems/TextSecure
In Stop thinking up startup ideas [presentation]
From browsing the source and referencing the architecture section of the wiki ( https://github.com/WhisperSystems/RedPhone/wiki/Architecture... ), there is a RedPhone master server (master.whispersystems.org:31337) and a relay server (relay.whispersystems.org:31337) that the phone will use during the course of all phone calls. Apparently, most cell phone network providers disallow direct peer-to-peer communication, thus the relay server is necessary to complete this kind of encrypted call. All of your encrypted voice data will pass through the relay server, so there isn't going to be much privacy in terms of who you are talking to at what times, but the contents of your voice call won't be revealed.
In RedPhone is now Open Source
