I'm having trouble getting a BCM400 to present CLI to an NTL Telewest exchange over PRI. Their support team tell me that I need to send 10 digits with national dialing plan. In Elements Manager under Telephony / Dialing Plan / Public Network I've got Public Received Number Length set to 10 and Public Network Dialing Plan set to National. No joy. Anyone know whether there are any other settings that I need to change? Is there a way to monitor what the BCM is sending to the exchange to try to diagnose the problem?
