A softphone application is provided that facilitates device switching between devices twinned therewith. In an aspect, a first device employing the softphone application generates a request to switch a media session between a second device and a third device to be between the first device and the third device and the softphone application sends, the request to an application server device associated with a cellular service provider identity. The request comprises a first identifier for the first device, a second identifier for the second device, and a device switch indicator. The request is configured to initiate a switch of the media session to being between the first device and the third device based on a determination that the first device and the second device are associated with a common mobile subscriber identity registered for an account associated with the cellular service provider identity.

Seamless movement of active media sessions between twinned communication devices

In one embodiment, a method for managing a Voice over IP (VoIP) network includes collecting a first set of data from a first source of network performance management data, each data item in the first set of data corresponding to a call made using the VoIP network; collecting a second set of data from a second source of network performance management data, each data item in the second set of data corresponding to a call made using the VoIP network and being of a different type than the first set of data; correlating the first set of data and the second set of data such that a data item from the first set of data is matched with a data item from the second set of data that corresponds to a common call made over the VoIP network; and outputting a performance report based on the correlating.

Method and apparatus for correlation of data sources in a Voice over Internet Protocol network

A method and apparatus that employ the use of CDRs to effectively monitor and proactively respond to network or service events that impact performance within a network are disclosed. For example, the method receives a plurality of call detail records (CDRs), wherein each of the plurality of call detail records comprises a plurality of fields. The method determines a n-field rule signature from each of the call detail records (CDRs), and analyzes the n-field rule signatures from the plurality of call detail records (CDRs) for detecting at least one network performance problem.

Method and apparatus for detecting network and service performance degradations using call detail records

A method and system of processing call detail records (CDRs) of multiple network elements in a communication network are disclosed. The method includes identifying at least one final attempt CDR out a plurality of CDRs from the multiple network elements by at least one type of network element. At least one master CDR is built from the identified at least one final attempt CDR. Further, at least one CDR from the plurality of CDRs is correlated to the at least one master CDR according to a correlation rule. Also, the at least one master CDR is then augmented with CDR data from the at least one correlated CDR.
