[otrs] Non-Admin Agents Adding Customers to the DB Backend

Hello, Is there a way to allow Agents, who are not members of the admin group, the ability to add customers to the built in Database Backend? We currently don't have an external database configured with all of our customers. When a customer calls in we would like our agents to be able to add the customer and then create a phone ticket. As a non-admin within a new ticket, I click on the "Options: Customer" Icon/Link and a window opens with the following: "Message: No Permission to use this frontend module!" Is this a permissions issue? I don't want to grant these agents full administrative rights. Please let me know if you have any ideas. Thanks, Ethan OTRS 2 on FC3
