Simple VoIP QoS Config

mzinz

Hi guys,

I'm trying to set up some simple QoS on a point-to-point T1 link. All I want to do is prioritize VoIP traffic over everything else. Here's what I have so far:

ip cef
!
ip access-list extended VOIP-TRAFFIC
remark --- Cisco VoIP Traffic
permit udp 192.168.201.0 255.255.255.0 10.25.0.0 255.255.255.0 eq 5004
!
class-map match-any VOIP-CLASS-INBOUND
match access-group name VOIP-TRAFFIC
!
policy-map VOICE-POLICY
class VOIP-CLASS-INBOUND

I realize that I haven't actually prioritized yet. My question: Do I need to set priorities for all traffic, or do I just need to put priorities for traffic that I want to treat specially? Assuming each call takes 100k, and there can be up to 10 calls at a time, what would be the best way to handle this?
