Hello ciscovoiceguy
Usually, no specific configuration is needed,it should be that simple :
1. Power on your wireless phone 7925 and connect it (Wi-fi) by searching or adding network SSID.
2. You can configure DHCP or you can go through static IP address assigned to the Wireless phone.
3. You should be sure that you can reach CUCM in order to complete registration from your configured IP address.
4. Do not foget to add Wireless Phone MAC address to CUCM.
Thanks,
Hisham
