Abstract
A dynamic global callback technique which is capable of maintaining a manageable number of incoming calls to a central location from a plurality of remote units. A plurality of remote units are prompted to initiate callback attempts to a central location during a given callback period. The number of successful callback attempts from the remote units to the central location is monitored. The callback period if dynamically adjusted so as to cause the monitored number of successful callback attempts to approximately equal the number of successful callback attempts capable of being handled by the central location without overloading the telephone network.
