Mobile phones have become a multifaceted device and different dimensions are added to it offering Value Added Services. One such VAS, facilitating call management is Missed call alert. The missed call alert is a lead generation value added service that allows mobile operators to equip the customers with an easy to use call log and notification system, for the calls missed while the called party was unreachable or his mobile device was switched-off. This, in turn increases their day-to-day call efficiency.

The missed call alert VAS service uses SMS to inform the receiver about the calls missed whilst they were not reachable, as well as to inform the calling party of the availability of the called party when they are reachable. The text message sent to the calling party can also be modified by end users. The number of subscribers to which the missed call notification is sent to, can also be controlled.
