To manually change the DNS servers that your Cisco WebEx Telepresence devices are using, you must set the IP assignment to static. Otherwise, you have to change the IP address on the DHCP server that services the WebEx Telepresence device.
Here are the instructions for changing the IP assignment to static mode and entering the DNS information.
