In a voice-over-IP communications network, call data records include dynamically assigned IP signaling addresses such as IPv6 signaling addresses used in provisioning communications sessions. Those dynamically assigned IP signaling addresses are computed from customer site identification codes using a reversible algorithm. The algorithm can then be reversed to compute a customer site identification code from an IP signaling address contained in a call data record, allowing the communications network provider to perform quality monitoring and diagnostics based on call data records.

Identifying the source and destination sites for a VoIP call with dynamic-IP address end points

A method and system for monitoring a packet network by using call detail records (CDRs) are disclosed. The method first receives at least one call detail record (CDR) at a completion of a call from at least one voice gateway router that serviced said call and analyzes said at least one CDR. The method then monitors at least one performance parameter in accordance with said at least one CDR.

Method and apparatus for detecting a network impairment using call detail records

A method and system for enabling a network service provider to monitor a packet network by using call detail records (CDRs) are disclosed. The method first detects a termination of a call by at least one voice gateway router and generates a call detail record (CDR) at said termination of said call by said at least one voice gateway router. The method then forwards said call detail record by said at least one voice gateway router to at least one CDR collecting and analysis server.

Method and apparatus for monitoring a packet network

Implementations described and claimed herein provide a method comprising generating a plurality of prompts, each of the plurality of prompts related to one of a plurality of elements, generating an indexed prompt file (IPF) comprising one or more of the plurality of prompts and index information about the one or more of the plurality of prompts, and generating an IPF map file relating one or more of the elements to one or more of the plurality of prompts using the index information. The method further comprises mapping a target phone number to the one or more of the plurality of elements, the target phone number being associated with a target on a target list, generating a call to the target phone number, and playing the one or more of the plurality of prompts based on the index information.

Customized message generation

A method and apparatus for providing asynchronous alarm correlation in packet networks are disclosed. For example, the method receives a trigger, and performs an asynchronous correlation of at least one root cause alarm with at least one symptom alarm.

Method and apparatus for asynchronous alarm correlation

A method is provided for monitoring devices with changing IP addresses. SNMP trap is received from a device at a first IP address to notify that a connection is up, and a SNMP poll is transmitted to the device to obtain an identifier. Predetermined consecutive SNMP GET requests are transmitted to the device in intervals. Responsive to failing to receive from the device predetermined consecutive SNMP GET responses equal to the predetermined consecutive SNMP GET requests, it is determined that there is a connection failure or a device failure and checked whether the device is in a maintenance window. If not in maintenance window, a trouble ticket is generated. Responsive to the failure, there is a predetermined waiting period for another SNMP trap from the device with a second IP address and the same identifier notifying that a connection is back up, and no trouble ticket is generated.
