Configuring Sub-interfaces and Setting QoS

[moneer.rifai]

Hello,

I have two Cisco routers connected with a T1 link using PPP. See the network diagram. The attached diagram explains what needs to be configured for the remote site.

Essentially, I need the remote site talking to the main site and I need phone traffic and traffic from one other device to be tagged with DSCP 46.

To do that, I need to configure sub-interfaces on Fa0/1 on router B and join them to the corresponding VLAN, is that correct?

What about QoS, what is the simplest way to configure that?

Here is the relevant part of show run on router B:

interface FastEthernet0/1
