Making and Receiving Secure Calls
During secure call setup, there is a progress tone and progress displays on the screen.
When secure call setup is complete, a completion tone sounds; you may now begin
talking. A secure call usually takes longer to set up than a clear call. For example, if the
called party is not logged on as a secure user when the call is initiated, the called party
will need to do so before the call can be connected.
The secure LED is lit when making or transitioning to a secure call. ∙In addition, there is a
red bar on the left edge of the screen that highlights the trusted information. Any
information not highlighted by this red bar is not secure, and should not be trusted.
