Configuring a Linksys SRW208P with VLAN and QoS for VoIP prioritization

Hello,

I’m trying to configure a Linksys SRW208P with VLAN and QoS to prioritize VoIP traffic.  I need a little (a lot, really) of help with the strategy and setup.  

The elements:
To the SRW208P switch we will connect 4x Cisco 7940G phones and the computers connect to the phones pass-through port.

Our PBX is a virtually hosted asterisk server.

As a router we are using a Netopia 3000 that supports VLAN but I don’t see any configuration for QoS.

Here is the current idea:

In the switch we will create the VLAN’S
VLAN 1: Management/Admin (if its necessary?)
VLAN 10: VoIP
VLAN 20: Data

The Cisco Phones will be connected to port 1-4

QoS in the switch will be setup to give VoIP Traffic the highest priority always.

Is this about right? And should I configure the SRW208P to achieve this.

I think it requires to have a QoS-support on the router. Native VLAN is important so you could still manage the switch interface. I think you need to use ESW series switches which supports CDP to negotiate the PoE to the phones. Also, you should have used a multi-layer router.
