Abstract
A method for identifying a route of a call in a telecommunication system (10) comprises the steps of routing the call from a telephonic calling device (12) via a telephonic switch (14) to a telephonic terminating device (56) and disconnecting the telephonic call. After the telephonic call is disconnected, a call trace is established to identify a called line number of a terminating line in response to a call trace request from the telephonic calling device (12) after the telephonic call is disconnected.
