A conference diagnosis system can correlate information about a current teleconference with information about past conferences to make an intelligent assessment as to the potential cause of a poor audio or other condition. A conference bridge conducting the conference can then change various configuration settings on the conference bridge to resolve the problem. A running average of the results of past adjustments can be measured and direct future configuration changes. Thus, past successful adjustments can provide a starting point for changes to a new conference and real-time digital signal processing (DSP) adjustments can help tailor changes to the specific conference.
