For each contact you communicate with, you can save their information as an entry in the contacts list. These contacts are added individually or by importing multiple contacts from another source. You can also export your contacts to a .csv file, a vCard file, or a .pst file.
When you first install UniTel Voice, and at any time in the future, you may want to populate the contacts from an external source such as a file of contacts in your Outlook address book.
