RADIUS Disconnect-Cause Attribute Values are listed here http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fsecur_c/fappendx/fradattr/scfrdat3.htm#xtocid1 but I couldn't find 1F. Interesting. Anyone know?

The voice-quality indicator is the ICPIF value (Calculated Planned Impairment Factor from ITU G.113) present in stop records. This statistical value is generated from the gateways measuring dropped packets, delay, and other quality factors; it is contained in the vendor-specific attribute (VSA) #31, with a value of 0 being the best.
