Call distribution evenly on gateways

We have 2 GMS gateways with SIM Cards Terminating calls - Same sims , same area code same rate.

I am trying to avoid overusing one GW so need to be able to distribute calls to both GWs , could be random but I prefer to send call1 to gw1, call2 to gw2 , call3 to gw1 and … .

I have created 2 identical dial peers ( same rate and same priority ) but it did not work. So calls still hit the dial peer with higher ID first.

I though it will work if priority is same ( both 100) . Is there a way to do this ?

Use gateway group

Works perfectly.
