you will not find a step by step guide, but here is a summary:
configure a class map to match voip traffic (rtp, rtcp, SIP).
create a policy map to apply the BW requirements either policing or priority..etc
apply the service policy on the interface required.

i need to put priority on voice traffic from 172.16.56.0/24 to 172.16.52.0/24
///I created an acl:

access-list phone_policy extended permit ip 172.16.56.0 255.255.255.0 172.16.52.0 255.255.255.0

///created a class map:
class-map voice_policy
match access-list phone_policy

Now what do I do?

then you can use the policy map to apply priority to the voice traffic, this ACL will be simple and apply the priority to all of the traffic (including |TFTP and CDP)
