A Q931 cause code = Q850. Just remember that it can be listed as binary code (debug cch323 h225), hex code (debug* *voip ccapi inout) and a high-order hex code (debug isdn q931). Keep in mind with debug isdn q931 the cause codes includes the digit origination point, a Q850 cause code then an optional diagnostic field ie: 0x818202, where 82 is the cause code.
Q.850 cause codes in debug isdn q931 use the high order-bit hex set, so when binary code = 1 then hex code is 0x01 the high-order hex set is 0x81. >From there is proceeds as expected, binary = 2, hex = 0x02, high-order= 0x82. The best reference table I have seen is in the Troubleshooting Cisco IP Telephony book which correlates all three into a single table.
