Updating the Domain Name Service server
If you configure a Domain Name Service (DNS) server for name resolution in
your network, you must contact your local network prime to update the DNS
with the new IP address of the Contact Center Manager Server.
ATTENTION
To verify that the new IP address is up to date on the DNS, use the ping <server
name> DOS command with the server name to confirm that the system responds
with the corresponding IP address.

Network Control Center server, you must update the IP address for the Contact
Center Manager Server on the Network Control Center server.
