IP configuration is incorrect or duplicated. RTC (Media Gateway) card has no IP address. The APC-MXe has lost communications with the Media Gateway (RTC). | Check that the IP addresses are correct by checking the System IP Properties form on the System Administration Tool. Refer to Mitel Knowledge Base article 09-5157-00026 for instructions on how to set the IP address. Ensure that the internal L2 Switch is operating properly.
