Setting up a Queue for Voice

I am looking to use Mikrotik router OS for my Hosted phone installs and need help setting up Queueing

I want to give priority to the Hosted phones, what is the best way to do this?

Internet is attached to Ether 1
Data Vlan is attached to Ether 2 with a 192.168.50.0/24 network
The Voice Vlan is attached to Ether3 with a 10.0.0.0/24 network
How do i properly setup a queue tree ?

Thank you

No takers?
