can someone explain to me how/where/if the incoming calls to a gateway have dscp/precedence applied.
I see within Clusterwide Parameters under services, on CCM that there are settings there, but are these automatically applied to calls coming in via a gateway, or is this something I need to do on each individual gateway.
Not sure if latest IOSes have changed the defaults from af31 to cs3. If not, you will need the following.
*** for mgcp gateways***
mgcp ip qos dscp signalling cs3
*** for h323 gateways****
dial-peer voice 3 voip
ip qos dscp signalling cs3.
