Hi
You don't need DNS, although it's easier if you do configure it.... You can add this to the CM server and set it up quite easily. Let me know if you don't know how to do this and want to...
If you don't want to set up DNS, then do the following:
1) Ensure you've set up the option 150 on your DHCP scope:
2) Go in the CallManager admin pages, under System/Server, then find your server. If it has the server name in the Host Name/IP Address field change this to the IP.
3) Anywhere that uses URLs (like Enterprise Parameters which has URLs for help/services etc) change the hostname of the server to the IP (i.e. from http://cm/help to http://192.168.1.1/help
