Every telecom operator defines a dunning process that is used to remind subscribes that their payables are overdue and to request payment. The Dunning Management System is a software package that:

• Handles all actions in a dunning process in one place
• Manages dunning processes by invoices or by subscribers
• Simplifies the workflow of dunning agents using only one application to monitor dunning processes and subscribers
• Interfaces to other telecom operator's components: the billing system, IN platform, SMS center etc.
