Basic VoIP

This is probably an easy one but here it goes...

We have the following setup:

phones --> CAT3750 --> C2851 --> WAN (eigrp) -->C2821 --> CAT6509

And we need to enable QoS.

As far as I know the following is need:

all ports that hte phones are connected to on the CAt3750 need : switchport voice vlan <vlan #>

and then all the routers\switches in between need the following: auto qos voip trust.

Is this correct? Is the auto qos voip trust on the global config or on each port connected to the inside & outside?

I am trying to enter auto qos voip trust but the router will not take it? For example the C2851 has Version 12.4(13r)T.

Please help
