Abstract

A fault tolerance call processing system is disclosed. The fault tolerance at the server level is achieved by shadowing between primary functional components and standby functional components running on a plurality of processors accommodated on several CT servers. The fault tolerance at resource level is achieved by allowing reallocation of resources from any circuit boards and platforms to process a call.
