There are numerous factors which can con- tribute to poor quality in a telephone interconnect call. Although fault management processes and tasks attempt to prevent the initiation of these calls, it is virtually impossible to eliminate their occur- rence completely due to the dynamic nature of the system's resources and configuration. A system which experiences high amounts of calls that are short in duration may exhibit problems that could not be detected by conventional fault management methods. A short duration call is a possible indica- tion that the integrity of the audio path is compro- mised leading the user to terminate the call prema- turely. Since it is not possible for a single network element to detect and diagnose all components pert- nent to audio quality (terrestrial circuits) RF circuits, voice processing resources, etc.), it is likely that faulty resources will be assigned multiple times before a problem is discovered.
