Would anyone happen to know of a database from cisco that can possibly allow me to input MAC addresses to get the serial numbers from cisco 9971 phones? Just curious as I cant remotely access the Call manager for a customer as they have version 8.5 and my browsers have compatibility issues with it. These phones were installed at the customer site long before i started working with the company and was before they began taking inventory in goggle drive (cannot find old inventory sheet). I tried using uplinx to get a generated report from the call manager but it gave me everything but serial numbers which was a drag. Thanks in advance!
