Abstract

A system for centrally and remotely testing switches of cellular and conventional telecommunications network wherein a controller located at a remote location provides instructions to Remote Call Processor (RCP) to thereby prompt the RCPs to establish a communication link from the RCP through a switch to a destination device whereby audio from said destination device is communicated, by way of the switch and the RCP, to the controller in order to verify that the switch properly routed and billed of the call. The destination device may be a service provided by such network or it may be another RCP.
