I need to prioritize the voip packets,I am trying to use class-maps mathced with access-list.
My dial-peer traffic originated within the router ( POTS phone) and has to be sent out over WAN.
It seems that any access-list is unable to catch Voip traffic. What is the best method to filter and modify (ToS filed) of this voice packets that are originated within the router ?

Hi,
It seems to me that the best way for you to proceed is to use ip qos (or ip precedance) command that was introduced for dial-peers. Please, take a look at:

You can specify the ToS (DSCP to be exact) for all the voip related traffic that passes through dial-peer.

Hi,
I am running IOS 12.1 and I cannot upgrade it to 12.2 due to memory limitation.
I can only set ip recedance in V-12.1.
So I try to set ip recedance in dial-peer, and tried
to catch it using class-map, then to modify DSCP using policy-map.
But it wan not successfull. What could be my mistake ?
