Discretio is an application (and service) for secure VoIP on smartphones. It allows users to establish calls over the Internet while using state of the art encryption technologies to avoid eavesdropping.
A filter feature for encrypted calls was added. If a call with Discretio fails, you can fall back to GSM. SMS and email invitations for downloading Discretio can now be sent. A new GUI was included. Incoming Discretio calls can now automatically unlock the phone. The registration interval was shortened to 10 min, and some connections bugs were fixed. Call establishment is now faster. Certificates are now validated by the client application. A SKI display option was added. A Bluetooth headset option for encrypted calls was added (though the Bluetooth connection is not secured). Various bugs were fixed.
