Abstract

Local call information data sets are obtained for each of a plurality of devices engaged in a call, the local call information data sets comprising call attributes and associated metadata. Call signaling is mapped by correlating at least one attribute pertaining to the call in each of the local call information data sets. Global end-to-end call state machine is generated subsequent to mapping of call signaling. The global end-to-end call state machine includes a plurality of global states. Each global state represents a local state of each device along with state transition indicating change in the local state of at least one device.
