2 seperate network connect to mikrotik 750gl

Hi Guys,
I need help connecting my voip phones directly to mikrotik and my lan directly to this device.

Setup for LAN

2 bonded DSL → MikroTik ->Sonicwall ->DHCP server

Voip Setup

2 bonded DSL ->Mikrotik → VOIP

The whole idea is to seperate the VOIP from my existing network, so both can share the internet.

Thank you, for your help
