I am a newbie so I apologize if this question has already been solved. However, couldn't find a direct answer in my research.
When I am calling a contact, the "secure button" in the caller field is red, and the mouse-over says "call not secure".
Now, I have found an exchange of messages o the user list (see here: http://lists.jitsi.org/pipermail/dev/2013-May/016961.html) where it says that the problem is merely a GUI issue; but they are talking about conference calls.
Could someone enlighten me where I go wrong, if indeed I do something wrong (I have the ZRTP turned to 'Standard')
Thanks much in advance
