Undesirable noise detection and management

A communications management system (CMS) and related method receive registration information related to a plurality of participant systems (PSs) that communicate audio information between themselves. The CMS transmits a unique signal to each of the plurality of PSs that causes each of the plurality of PSs to produce a unique audio signal and detects an undesirable sound (US) in a PS of the plurality of PSs responsive to the transmission of the unique signal. Then, responsive to the detection of the US, the CMS applies a remedial action to the PS to initiate a reduction in a likelihood that the PS will produce a future US. Finally, the CMS repeats the operations of transmitting, detecting, and applying according to a predefined testing criteria.
