I am trying to configure 2811 Gateway for IP to IP VoIP calls as a carrier and need to calls to be Authenticated/Accounted on Radius Billing Server. The problem is that when a call comes into the GW, the call is forwarded on the second leg without authenticated but the accounting messages are coming properly.
Cisco TAC advised that I need to run TCL which I don't understand why. I am NOT using any IVR for the incoming calls, but still they insist using it.
Anyone has any experience in this implementation.
