One common scenario is having an assistant organize a call on your behalf. Calliflower gives you the ability to "delegate" your call creation rights to another, so that person can create, edit and manage calls just like you. In order to do that the person acting as your delegate must also have a Calliflower account, although they do not need to have a premium Calliflower account.
To designate a person as your delegate:

1. Search for that person in the address book. Simply type the person's name into the address book. If they are not already part of your address book on Calliflower, enter their details, and Calliflower will then match that account with the person's account.
2. Once the account has been found, to the right you will see the account details for that individual.  Underneath, you will see a check box allowing you to delegate call creation to that person.  Click it to mark it yes, and then simply press the save button.
