ABSTRACT:
The present invention is drawn to a call trace system and method that is simple to establish in a short amount of time. The call trace is implemented through a Web browser page which remotely programs central offices to trace calls to particular number. When a trace is established a message is sent back to the Web browser which displays the calling number, the called number and the central office detecting the call. Also, a page is sent to a pager which displays the traced information.
