ClearOne Max Wireless Conference Phone

Wireless, conference room speakerphone.  Works with your home phone line.  I bought this when I was working from home a few years ago.  My new company uses video conferencing so I don't need it anymore.  I have all the parts (charger not shown in pictures) and the battery seems to be working.  This is model 860-158-400 Rev 2.2 and some more specs can be found here:
