I bought an ATA 190 from eBay. Open box. Appears brand new. But there is no configuration menu. No Quick Setup or Network Setup. Reset just brings the same old menu. On the back is has a label from ANATEL which is Brazil's phone network. I'm a home user so I don't have any access to CUCM which might be able to see this device. Is there any application, like Putty where I could download vanilla firmware to be able to use this device, or is it now a paperweight? Thanks for any help.
