30 Making and Receiving Calls Preliminary Draft
When you make a secure call, your phone searches your phone
book and history list to determine the following about the number
you are calling:
■ If it has previously been entered as secure in your phone book
or has a secure number associated with it in your phone book
(Many numbers entered in your book have both a clear
number and a secure one).
■ If it was recently called and designated as secure
If not designated in your phone book or the history list as secure,
your phone sends signals to the other phone to check that it is a
secure number.
This checking process is referred to as “call setup.” The first time
your phone performs this setup with this number, your phone
takes longer to make a connection. You will see additional
messages and may need to respond to a few messages, such as
noting the “Received certificate expired.”
If a secure connection is made, you’ll hear a beep and a message
appears confirming the security level of the person you are calling
or if the level is “Protected,” the screen displays the PGP
fingerprint. If a secure connection cannot be made, a message
appears confirming to continue as a clear call.
If the number you are calling is in your phone book as a clear call
and a secure connection is made with this number, it is sent to
your phone book and your phone will not perform the setup again
for this particular number.
If the number is not in your phone book, you will be disconnected.
Enter the number you are calling in your phone book (see page 36)
and try again or call the party again as a clear call.
Redialing calls
After you have made a call, you can redial in one of the following
ways:
■ Redial the last number you just called
■ Retrieve from your history list
To redial the last number you dialed
You can easily redial the last number you phoned by simply
pressing the Send/Talk key from the Home screen. Of
