asterisk users - Apr 2009 - Extract a MOS value from Asterisk CDR

Hello all,
I'm tring to retrieve a formula to calculate a MOS value from Asterisk RTCP 
stats...
Have you got any idea how to do it?
Thanks

I'm reading all G.107 ITU docs to retrieve something...

I'm saving the SIP RTCP stats with:

[macro-hangupcall]
exten => s,1,Set(CDR(userfield)=${CHANNEL(rtpqos|audio|all)})
exten => s,n,ResetCDR(vw)
exten => s,n,NoCDR()

So I retrieve these values in my MySQL CDR table in order to calculate a MOS 
value: 
"ssrc=592614191;themssrc=0;lp=1;rxjitter=0.000000;rxcount=0;txjitter=0.000000;txcount=20734;rlp=0;rtt=0.094000"
codec used: g711a
