Abstract: A method includes receiving multiple alarm messages, each being associated with a failure associated with a service feature available within a telecommunication network. A failure rate for a type of failure having a common set of service feature failure characteristics is determined from the alarm messages received. When the failure rate exceeds a threshold, a maintenance ticket is generated automatically.

Abstract: Method and apparatus for re-routing a call in a packet network during failures is described. In one example, a failure condition is detected for a destination endpoint for the call. At least one alternative endpoint address is identified from an alternative routing plan registered with the packet network in response to the failure condition. For example, various alternative routing plans may be registered with the packet network and stored in a database. Each of the alternative routing plans may include alternative endpoint address data for a plurality of endpoint devices. The database may be queried using the destination endpoint as an index value and the at least one alternative endpoint address may be retrieved. The call is then routed to the at least one alternative endpoint address.

Abstract: A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.

Abstract: A telephone network voting system receives telephone ballots cast by voters by dialing a telephone number. The telephone number is dialed by voters spread over a large geographic area. The voting calls are routed to points of presence local to or otherwise identified with the caller by using the caller's ANI or other originating number identification. The points of presence then accumulate votes and periodically forward tallies to a centralized location over a data network. Instructions may be transmitted from the centralized location to the points of presence.

Abstract: The present invention is directed to mechanisms for content-aware redirection and content exchange/content discovery that permit a request for content to be redirected to a particular advantageous server that can serve the content.

Abstract: A method for providing combined local, toll, toll-free services, and number portability, to a calling party originating calls from an IP-based communication devices which are coupled to an IP-based multi-media service provider. The method includes receiving a SIP INVITE message, which includes a multi-media service identifier, at the multi-media provider. The SIP INVITE message represents a call request for a multi-media service. The SIP INVITE message is processed at the multi-media service provider for determining if the call request can be satisfied. If the multi-media service provider includes resources for satisfying the call, the multi-media service identifier of the SIP INVITE message is set to a first predetermined state and the call is processed. If the multi-media service provider does not include resources for satisfying the call, the multi-media service identifier of the SIP INVITE message is set to a second predetermined state and the call is processed elsewhere.

Abstract: A method includes issuing a retrieval instruction, such as a database query, to retrieve from a database system a datum associated with a network circuit established outside of the United States. Upon receiving the datum from the database system, it is determined, based on the datum retrieved, whether the network circuit is incurring a charge. It is further determined, based on the datum retrieved, an amount of revenue generated by the network circuit. When the amount of revenue generated by the network circuit is below a predetermined threshold, a termination instruction to terminate a service associated with the network circuit is issued.
