Abstract
Abstract The system and method for tracing a path of a call through a telecommunications network includes at least two switches, a database, a user interface device and a control processor. Each switch has an associated adjunct processor that has a memory that stores call record data. The database stores call routing data for calls traversing each switch. The user interface device accepts selected call parameter data related to a call having a path through the telecommunications network that is to be traced. The control processor accesses the call routing data and the call record data for searching for a call having call parameter data corresponding to the selected call parameter data. The control processor provides report data that is related to the path through the telecommunications network of a call having call parameter data corresponding to the selected call parameter data.
