HOME > Products & Solutions > Prepaid Solutions > User Interface > Overview IVR-like Media processing function and control enables us to make a unique, end-user friendly interface. All of our switch platforms provide this feature, which is the most advanced and the best ease-of use interface. In addition, the traditional prepaid calling card scenario works too. This patent pending feature provides a speed-dial/short-dial storing function. Numbers can be stored - and then used for speed-dial/short-dial - by the customer pushing the desired button for a long period of time during the conversation. Provide your customers ease-of-use ANI registration for the PIN-less dialing feature. No separate dialing is required by the customer. No IVR is required by the service provider. To keep the registered speed-dial/short-dial information and registered ANI information, customers normally tend to recharge the original PIN numbers. However, the customer can recharge the PIN number by providing an unused PIN number.
