  • Patent number: 9231837
    Abstract: Methods and apparatus for analyzing, collecting, and presenting data in a communication network are disclosed. An example method includes analyzing collected data to generate gateway metrics representative of a user experience of a user-initiated communication within a network, the network comprising network elements, the gateway metrics comprising at least one of a number of termination attempts for a DS0 channel, a number of rejected attempts for the DS0 channel, a number of terminations answered for the DS0 channel, a number of attempts for a hunt group, a number of rejected attempts for the hunt group, or a number of terminations answered for the hunt group; determining an average upper transaction time per customer based on the collected data; and presenting the gateway metrics in a plurality of tabular views corresponding to service area levels, the views presenting performance data representing the average upper transaction times of the service area levels.

  • Patent number: 8867526
    Abstract: A method and an apparatus for providing mobility for a Voice over Internet Protocol Service (VoIP) provided on packet networks are disclosed. For example, the method receives a register request from a user endpoint device and retrieves an Access Point-address parameter from a contact header in the register request. The method then determines a physical location of an access point device in accordance with the Access Point-address parameter and updates location information for the user endpoint device in accordance with the physical location of the access point device.

  • Publication number: 20070115935
    Abstract: In a particular embodiment a system and method for processing a call in a Voice over internet protocol (VoIP) network are disclosed. The method includes receiving the call associated with a private identifier (PRID) at a server, classifying a call location based on the PRID and sending the call from the server to a Public Safety Answering Point (PSAP) with a call back number associated with the PRID. The system includes a first server interface for receiving a message containing a PRID associated with the call, a second server interface to access the data base for searching for the PRID in the data structure; a third server interface to receive an output from the database indicating whether a PRID has been found in the data structure; and a fourth server interface to send the call to a PSAP.
