SysMaster (Radius)

we have a sysmaster SIP proxy,it’s a all-in-one solution including radius/gatekeeper/billing/web-based server solutions over a linux OS. We’re connected to AT&T Fiber and Local Telecom Fiber as normal. But whenever a client tries to make a call to another client it uses unnecessary bandwidth because of authentication by sysmaster. we want to built another radius server parallel with sysmaster’s database, so whenever a client makes a call, it goes to primary radius, checks it with database and in case of a local call to another client, automatically routes the data to client without using Local Telecom Fiber. Is there any solution or idea for solving that case.

Thanks…
