Pass Voip traffic from WAN 1, have Done 3 WAN Load Balancing and Fail Over

Hello friends,

I have done a load Balancing using 3 WAN. I have 2 shared connection but 1 is dedicated now i just want to pass my VOIP traffic to a dedicated connection so what is the possible solution for that Please Guys Guide me.
Thanks

How do you identify VOIP traffic,
source address?
→ is it contained with a subnet, if so routing rules,
→ is it contained within a few IPs, if so routing rules

Destination address
→ is it contained with a subnet, if so routing rules,
→ is it contained within a few IPs, if so routing rules

Anything else is likely going to need mangle rules.
