An understandable and convenient IVR is part of proper corporate style. It makes the company convenient to reach and raises its prestige in the customers' eyes.
An IVR's scenario can include a greeting, a voice company presentation, information about current promotions and discounts. The customer receives the information in the automated mode, but he can also choose to talk with a manager.
Subject to integration with billing systems and CRM, personalized greetings, calling customers by name and self-service systems (balance top-up, service activation/deactivation, checking order status etc.) are possible.
