I've got a digital phone system but it goes VoIP across our P2P T1's. I am having quality issues between our 2 sites only and have decided to setup QoS on the Cisco 1841 P2P routers. Since it is only 1 phone server on each side that does the voice traffic, I would like to do QoS by IP address, instead of by protocol. So if I understand correctly, I will need an access-list, a class-map and a policy-map and need to point the interface to the policy-map. I'm drafting a config but have hit a few mental bumps in the road so can anybody give me an example config based on best practices? Thanks!
