QoS (?) for Cisco 1721 Router

Humper

I have Vonage VoIP and I would like to setup QoS (I think this is what it is) on my router. Basically I want to ensure that there is 100+Kbps set aside (ALWAYS) and make sure the VOIP packets are set to the highest priority.

Could anyone point me in some sort of direction on how to do this? I searched at ciscos website and found QoS Device Manager but it looks like I need to install it on a server???

Thanks alot in advance!

Use class based qos.

Class-map Vontage_Data
match ip dscp ?? ( depends what value you phone is marking in the ip packet,you will have to check this maybe its ef)
Class-map Vontage_signalling
match ip dscp ?? ( same as above but this is for the signalling, less priority, maybe af31)

Policy-map Vontage
Class Vontage_Data
priority 100
Class Vontage_signalling
bandwidth 64
Class class-default

Then on the interface use define the policy-map using
Service-prioriy output Vontage.

Anyway this is just to put you on the right track,maybe check out the "Auto qos" feature.
