Load balancing

[alaa.musa]

I have 2 AS5300 Voice gateways , connected to the same PSTN , i need to distrubute the calls between them equaly , round robin , how i can do this , in my site i have only these gateways no additional routers

I think that duplicating a dial plan that points to different Route Groups and putting half your users in one and half in the other will be a good solution.
