QTrace is your window on the network. Focus on any subscriber or any network activity in minute detail, using custom-defined filters: view and define specific traces quickly across data, voice, and VoIP, both historically and in real time. QTrace displays a correlated end-to-end call trace of a subscriber session or a network issue. This helps engineers investigate and resolve the root cause of subscriber complaints, allowing for accelerated problem solving. QTrace also provides critical data to third parties, expediting the resolution process for roamers and network vendors.
