Cisco SPA 112 VOIP Phone Adapter

If you are having trouble hooking up your Cisco SPA 112 phone adapter to your active directory domain, you are not alone. The SPA 112 doesn't play nicely with Microsoft AD. To get around this problem, you have to have an alternate way to assign it an IP address. I hooked it up to a standard off the shelf wireless router by an Ethernet cable, and then logged in to the router and saw the dynamically assigned IP address for the SPA-112. From there, you just plug in your laptop to that same router get an auto-assigned IP address, open a web browser, point to that IP address assigned to the SPA 112, example http://192.168.1.2 , and from within the SPA's control panel, assign it a static IP that matches what you want it to be on your AD Domain.
Once you have applied the IP, Save, and then close the browser. Take the device off of the wireless router and move it to your AD wired network. Once the SPA boots up, it will be part of the domain using the newly assigned address.
Then you can log in to it using the static IP you assigned it and configure it for your hosted VOIP platform.
