The QoS SRND states that the "auto qos voip" command adds the following config 
to the router:

C2970(config)# mls qos
C2970(config)# mls qos map cos-dscp 0 8 16 26 32 46 48 56

Earlier in the SRND, around page 40, it says that the old marking for audio 
signaling was AF31 (26).  That is the same DSCP marking listed above.

As part of our "best-practice" scenario, should we be changing the command to 
consider audio signaling as CS3 (24)?  The command would need to be modified:

C2970(config)# mls qos map cos-dscp 0 8 16 24 32 46 48 56

Is this true?  Otto, can you weigh in on this one?

Thanks!
