[cisco-voip] Setting up voip for wan edge

[Mike Reilly]

I am confused on when use the
class-map match-all VOICE
match ip dscp 45
class-map match-all VOICE-CONTOL
match ip dscp 26
 
 
or
 
class-map match-all VOICE
match ip dscp asf
class-map match-all VOICE-CONTOL
match ip dscp ef
 
What is the benefit of one over the other?
