We have some Atlas 830's set up to have PRI's. When ever there is an incoming call, it puts it on channel 23 1st if B-Channel Selection is set to normal. This causes issues as the customer's phone system send out going calls out channel 23. Is there a way to have it select channel 1 1st for incoming calls? We don't want to use circular because it will still have the issue one out of every 23 calls.
