Hopefully an easy one here. 2801 router with 4 FXO trunks. Customer insists that callerid and number should show up inbound. Is there a debug I can run on an incoming call that can verify that telco is sending this info down the trunk. "caller-id enable" is configured on the voice ports and I didn't think there was much else to do. This is a 2801 CME with a mix of 7975, 7962, and 7911 phones. Of course, I could go onsite with an old analog display phone, but that involves a 2 hour drive--a nice debug would be a good start. Thanks.
