VOIP VLAN and Subnet using HP 2910al

I want some advice on the best configuration for my LAN in preparation for an upcoming Mitel 5000 VOIP system installation. I currently manage a network with one secure subnet on using an ACL on one of my HP 2910al layer 3 switches. Ideally I want to create another subnet soley for VOIP. VLAN 1 default is for users and they are assigned an IP via DHCP scope -, the second scope is -, this is VLAN 10. My aim is to provide all ip phones an ip range of -, creating a third scope. I have two Cisco routers which are managed by my hosting provider, these are setup using HSRP. I have 3 HP 2910al layer 3 switches as the core, with 6 HP 2520-24 port POE switches to provide power to these ip phones. Happy to provide configs of any switches and I do have the configs of the Cisco routers from my provider. Help appreciated.

I'd say a rough checklist would be:
- set up new vlan for voip on switches,
- set up core layer3 switch as gateway for new vlan/subnet,
- set "voice" statement for new vlan to provide qos,
- set up dhcp/dhcp-relay on core layer3 switch as necessary,
- if NAT is necessary, let the router admin know that you'll need NAT for the new subnet.

Thank you. My plan is to add vlan 20 as VOIP vlan. On my root switch I will add ip routing and create an ACL to allow clients not on subnet access to my MITEL server which will have a 10.0.0.X ip. On VLAN 20 VOIP I will add the voice tag and ip of and the ip helper tag. I just need to make sure I tag the correct ports, for 2 vlans to operate on one port one must be tagged and untagged. Think I have a plan. Thanks again.
