You need to make sure sipx domain lists ONLY your valid intranet subnets. By default it lists three large subnets. If sipx talks to the provider on 10.x.x.x and goes through NAT, you need to remove 1he 10.0.0.0 subnet and address this first. If it does not think it is talking via NAT it will send it's internal address via sipxrelay (the media relay function). The subnets page is where that is determined.
