[Asterisk-Users] codec voice quality ratings

[trixter aka Bret McDanel]

Has anyone done any quality measurements on the codecs as implemented in
asterisk?  Specifically something along the lines of:
MOS (mean opinion score) either 1-5 or 1-10 variant
DAM (diagnostic acceptability measure)
DRT (diagnostic rhyme test)

Obviously MOS is the easiest, and network, speaker and microphone
quality can affect the results, but I would be interested in seeing
something done which goes into detail about the equipment used in the
test and the sample pool used to test it.

Anyone have any references for this?
