ABSTRACT:
A convergent network with voice over Internet protocol (VOIP) and voice over wireless local area networks (VoWLAN) telephones provides users a way for notifying a network administrator of a quality problem in real time together with an indication of the nature of the quality problem. Upon receipt of the notification, the system takes a snap shot of the current network parameters that are associated with the quality problem and provides network statistics for subsequent analysis and troubleshooting. Other callers participating in a call are also notified of the source of the quality problem. In addition, when streaming video or audio users detect a network quality problem, the problem is marked and tagged to indicate the time and the type of quality problem as it is occurring.
