The CiscoUnifiedCME router cannot communicate with CiscoUnifiedCMEphones if the IP address of the port to which they are attached is not configured.
Normally when you configure basic telephony-service parameters, then phone can register with CMEalthough no DN will be assigned to them. You can disable this by using the no auto-reg- ephone command.
