After the applications of the two users have exchanged and verified the security keys you can start the conversation.

Security control

A PrivateWave phone call is always encrypted. The protocol provides verbal verification of two keywords displayed at the beginning of the conversation. If both parties see the same keywords, then the call is secured:

The keywords change with each call. If the keywords are not the same between caller and callee hang up the call immediately because this may be a sign of a security attack.

After verbally verifying the keywords you can mark the contact as "reliable" by clicking on the red question mark. Verbal verification is not necessary for subsequent conversations and the keywords will be displayed in green:

In the case of calls to and from a landline telephone system, conference room or three-way call there are no keywords but only the security indicator. Buttons are also available for additional call transfer and three-way call services:
