Cisco IP Phone Inventory Tool: Inventories Cisco SCCP IP phones->outputs .CSV file with the following information: IP Address, Model Number, MAC Address, Host Name, Phone DN, Phone Load Version, Phone Serial Number, and switch name, ip, and port information.
The latest version (0.11) is now out! It include standard access to the phone's XML interface for standard access to all phones regardless of Localization and Firmware Language settings (currently with some exceptions).
Future Roadmap:
~Version (0.12) - AXL interface access to the CUCM databases to access the IPs of devices registered to the CUCM. This will negate the necessity of subnet scanning and phone IP lists.
