The company that i work for got a new voip system. I have connected two branches together using mikrotik rb433's

On router 1 i am using routing marks and policy routing. I have set 192.168.12.0/24 to use gateway marked as "KKT". The routing is working 100% correct but here is what i want to do.

192.168.12.2 is a computer.
192.168.12.3 is voip phone 1
192.168.12.4 is voip phone 2

What i want to do is set 192.168.12.2 to use gateway marked as 'KKT' and set 192.168.12.3 and 192.168.12.4 to use gateway marked as "VOIP".


I think that one option that i have is to create two subnets(192.168.12.0/29 and 192.168.12.8/29) Then to change 192.168.12.2 to 192.168.12.9.

Then allow 192.168.12.0/29 to use gateway VOIP and allow 192.168.12.9/29 to use KKT

PS: Both 192.168.12.3 and 192.168.12.4 need to connect to 192.168.0.3 and 192.168.0.4.
So can i add two gateways to the gateway marked as VOIP.
