The gateway can still register to the call agent even if the gateway is not registered in the CCM database. But placing or receiving calls or doing pretty much anything will not function until the gateway is configured in CallManager.
Whatever it says for MGCP Domain Name at the top, copy that to the clipboard. Then go to the gateway configuration in CCMAdmin for the gateway. There is a field there called MGCP Domain Name. Paste into the field, click Update, then reset the gateway.
Actually, it may look misleading, but the MGCP Domain Name configured in CallManager has nothing at all to do with DNS resolution.
The MGCP Domain Name on the gateway is actually used during the MGCP registration process. So that is the name that CallManager must have in the database in order to match up the registration attempt with a device in the system. That is the reason they must be the same.
