Documentation on Command Results: show rtp quality-monitoring call-history detail

[Anonymous]

I have been unable to locate any official ADTRAN documentation which explains the comprehensive results provided by this VQM-related command. The result contains 66 lines of values for each RTP stream. It looks like there is some great information for troubleshooting. Some of these parameters reported are self-explanatory. However, MOST have no definition/explanation provided or available (apparently anywhere!).

The document entitled: "Understanding Call Quality Statistics in AOS" (6AOSRG0005-30A) is no help as it does not contain this this level of information. Likewise, "ADTRAN OPERATING SYSTEM (AOS) Command Reference Guide AOS Version R10.9.0" (60000CRG0-35K) is not helpful.

Is there a document available that provides details on the results of this command?

It sure would be nice to have ONE document that contains details on the output shown below.
