Abstract:
1. A method of providing electronic surveillance in a telecommunications system, the method comprising: passing an outgoing correlation key, wherein the outgoing correlation key is associated with a first call leg directed to a second switch by a first switch; receiving a destination identifier and an incoming correlation key, wherein the incoming correlation key is associated with a second call leg directed to the first switch by the second switch; correlating the first call leg directed to the second switch by the first switch and the second call leg directed to the first switch by the second switch via the outgoing correlation key associated with the first call leg directed to the second switch by the first switch with the incoming correlation key associated with the second call leg directed to the first switch by the second switch; and as a result of at least correlating the first call leg directed to the second switch by the first switch and the second call leg directed to the first switch by the second switch, sending an electronic surveillance message indicating the destination identifier.
