We believe in the principal that everyone’s communications when expected to be private, should be private, and should be a standard. You wouldn’t sign in to your email account over plain text, so why expose your voice and test messages to the same exposure. The calls you place and receive will be forced SRTP for the audio content and TLS for the signalling encryption. This way your communications are secure to and from our network. On-NET calls and SMS are user to user, off-net calls and SMS are point to edge encryption. ZRTP support is currently in BETA testing. Let us know if you’re interested in participating in that program.
