Frequent List
The Frequent list is displayed on the Dial tab above the dialpad. It displays your outgoing call phone numbers. Unlike the Sent calls list in the Call log, entries are only listed once, no matter how many times they have been called. If a name is associated with the number, the name is displayed instead of the phone number.
