    Cisco SPA112 reviews

    SPA112 2-Port Phone Adapter is rated 4.7 out of 5 by 7.
    Rated 5 out of 5 by from Excellent adapter We used this to provide dedicated faxing ability over a hosted VoIP solution. Most of the time, faxing over VoIP is problematic at best, and we had tried with another ATA adapter with no success. This device has performed flawlessly in the time we have had it installed. Sending and receiving faxes has gone without issue. Would highly recommend!

    Rated 5 out of 5 by from Worked as specified. Nice VoIP option. Worked great......BUT you need to know what you are doing! < vbg> The adapter is only one minor portion of installation and set up. The tedious part if knowing the parameters, that are different for each provider. Luckily, I chose a well known and documented provider/vendor and did it all myself in under 30 minutes. Plugged the adapter into the router, NOT directly into the incoming modem. Hence, did not have to use the internet pass through on the adapter.

    Rated 5 out of 5 by from PIece of Cake... 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.

    Rated 5 out of 5 by from SPA112 2-Port ATA by Cisco 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.

    Rated 4 out of 5 by from So far so good 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.

    Rated 5 out of 5 by from Great Unit for the money This is a very economical way to convert SIP trunks for use with legacy telephone systems.

    Rated 4 out of 5 by from Works Perfectly w/Analog Phone I am using this with Callcentric and my existing analog phone after cutting my land line.� I still wanted a traditional home phone and not just rely on my cell phone.� I had ordered the Obihai device but there was static in the background.� Reading some forums it sounded like some devices had that problem and returning it was recommended.� I did that but decided to try this Cisco adaptor instead.� No static.� It was easy to set up, just following the Callcentric instructions.� Call quality is about the same as my land line but my bill is less.� �The only small issue is that when I change the UI setting to HTTPS vs. HTTP the responsiveness of the GUI slows waaay down.� Not sure why it does that but its a pain.� Once you have it set up, it's not like you have to use the UI/Admin screen all the time but it's still an issue so I removed a star for that.� One other difference I noticed between the Obihai and this one: fewer errors in the logs.� I send my log to my synology Nas.� With the Obihai, I would get periodic reboots and various log errors.� Far fewer issues with this Cisco so that gives me more confidence.� I know some people have had good success with the Obihai so maybe I just had a defective one that a replacement would have solved for but like I said, decided to buy this one instead of risking another failed device.
