            Comments about Cisco SPA112 2-Port Phone Adapter:

            Setup was easy, I am with Teliax, it took few info's about proxy and user ID and password and I was connected, my old Linksys PAP2 hit the dust after years. Just make sure before you do anything else to go to CISCO Support Web site and download newest firmware. Only minus is kind of sluggish Web UI in sense it take times to responds clicking on any hyperlink within settings page.

                Works flawlessly with CallCentric. They have the full setup info right on thier site for several ATAs including this one. Update the firmware to the latest off the website before doing any configuring first. I minimized all call compression; set defaults to use 711u codec.

                  Comments about Cisco SPA112 2-Port Phone Adapter:

                  I wanted to use this with a voip service that I have signed up with online. The setup seemed to be pretty straight forward, but that didn't work. But then I found some info on my voip service provider specifically for this unit, and after that I was up and running within a minute. I have only been using for a few days, so I can't say much, but the sound quality is pretty good, and the setup is pretty easy if you know what to do.Hopefully for most people it will be super easy. I updated the firmware on it and even that was a breeze.

                  I just wish the printing on the back was in bigger text. Hard to see the phone line 1 and line two when I have it tucked away behind my desk and I am trying to plug in the phone to it.

                  For my use case it didn't give me any big benefits over their cheaper previous model.

                  I tried to contact customer service to get a different power adaptor, and they wanted to play 20 questions with me. I know companies can use better customer profiles for their planning, but don't thrust that on us. it should be optional. Shame on you Cisco. You just lost a sale.
