    Although it doesn't matter what source IP voice & data packets have since you seem to already know the voip server IP(s), why would you need to put your computers behind the phone sharing the same 1G or 100M cable while you have a good looking switch with enough ports? You just need to pull another cable(s) to the computers. It makes the switch and FG30E difficult to handle QoS on the LAN side efficiently.

    For the question, you just need to have a static route for the voip server IP(s) toward WAN1, while the default static route is going toward WAN2. If you want to let them failover each other in case the circuit problem, you need to set a set of lower priority static routes to the opposite side then set link-monitor and let those high priority static routes to go away.

    I need to put the computer on the phone because I don't have any LAN ETHERNET available to put the computer alone.

     

    Even though I keep the computer on the phone, it's possible to do it?

    Regular routing works based on destination addresses. If destinations are different you don't have to use policy routing based on sources and other parameters.
