Method and apparatus for identifying telephone callers who have been unsuccessful in reaching a called destination
First Claim
1. A system for identifying one or more calling parties who were unsuccessful in reaching a called destination, the system comprising:
- a collector for collecting information about call attempts and call completions by each calling party to the called destination, wherein said collector collects call attempt information from a first network management system responsive to a local exchange carrier terminating said calling parties, collects call attempt and call completion information from a second network management system responsive to a local exchange carrier terminating said called destination and collects call attempt information from a third network management system responsive to an interexchange carrier network interconnecting said local exchange carriers; and
an analyzer for comparing the call attempt information with the call completion information to determine whether any of the one or more calling parties experienced at least one call attempt failure without also experiencing a subsequent call completion to the called destination.

Abstract
A system identifies calling parties who are unable to successfully complete calls to a called party. Call attempt failure records are retrieved from a local exchange carrier that services the calling parties, from a local exchange carrier that services the called party, and from an interexchange carrier that carries calls between the two local exchanges. Call completion records are retrieved from the local exchange carrier serving the called party. The failure records are compared to the completion records to determine which calling parties experienced one or more failed call attempt to the called party, and of these calling parties, which parties also failed to complete subsequent call attempts to the called party. The system also reports the intensity of calls made by these parties to the called party over a specified time period.

9. A method for identifying a calling party whose call attempt to a called destination is unsuccessful, wherein the calling party is terminated by an originating network interconnected to an interexchange network and the called destination is terminated bv a destination network also interconnected to the interexchange network, the method comprising the steps of:
-
collecting call attempt data independently from a first network management system supporting the originating network, a second network management system supporting the interexchange network and a third network management system supporting the destination network;
collecting call completion data from the third network management system supporting the destination network;
storing the call attempt data and the call completion data; and
comparing the call attempt data and the call completion data according to pre-determined criteria. - View Dependent Claims (10, 11, 12, 13, 14, 15)
