I had a vague need to audit the Cisco IP phones, so had a look for a tool to do it. And I found one, the rather appropriately named ‘Serial Grabber‘.
It basically walks your network subnets with your phones in, opening the little HTTP server on each phone (so you’ll need that enabled). It then basically screen-scrapes each one to gain info about what the phone is up to. You can then export the results for your own uses.
It looks good, and it’s a freebie. Apparently the developers parted ways from each other and the code was released as a freebie. Rare you find something related to ‘free’ and ‘Cisco’.
