Review: Good ATA! - This little adapter is a lifesaver! I needed to connect my two office phones to my VoIP service, and this thing made it super easy. Setup was a breeze, and now my calls are crystal clear. It's small and unobtrusive, and it just works. Highly recommend it to anyone looking for a reliable and affordable way to connect their phones to VoIP.
Review: Easy switch from Obi.. - I had Obi for several years, and used both Google Voice & Callwithus with it. I was very happy, until suddenly I couldn't use either account on the phone. I started to investigate, and realized that Obi sprung out of nowhere a required fee of $10 annual "premium technical support". Without paying this new fee, I wouldn't be able to continue using my accounts. Of course I tried to investigate online for a solution, nothing worked. I emailed their support center anyway asking for help, they wouldn't unless I paid the annual $10. It is a matter of principle for me not to pay such a dishonest company who uses bait & switch tactics. They can offer their box with the required annual technical support fee to new customers, but to do this to existing clients who bought this equipment knowing paying for the box is all they will ever need is very shady. I decided to look around for another adapter. The bad news, I wasn't able to find something that supports Google Voice. The good news, I did decide to get this adapter, and it was so easy to set up with Callwithus and it works beautifully. The manual is a bit confusing and at first I wasn't sure how to set up. But it is very easy. 1) Connect the box to power/phone/internet. 2) From the connected phone dial **** 3) From Menu option choose 110# and write down that number (for checking IP address for WAN port) 4) In the address bar of a browser page write that number and press enter. 5) The user & password are: admin 6) All I had to do in order to add my Callwithus account was input the proxy, user name & password of my callwithus account. I'm attaching a pic that will show where I put down that info. I didn't touch any of the other fields that already had values in them. That's all I had to do in order for everything to work smoothly. I don't think Cisco will get into the business of not providing needed software updates unless you pay them annual fee. I'm happy with using callwithus and from time to time use Google Voice through the computer (you put the # you wish to dial, then they call your phone and connect you to that number. Not as easy as picking up the phone and dialing, but for me it's worth it as I don't like to support greedy CEOs).

### ⭐⭐⭐⭐ This ATA replaced a 10 year old SPA adapter that ...
*by A***Y on December 1, 2016*

Update #3: Well, finally, this ATA has been working fine for a while now, with Caller ID and no problem with incoming calls. It is very quiet and the calls sound good. It really is a good value for the money. I officially have increased my rating to 4-1/2 stars, the 1/2 point demerit because I had to dink with it (with NAT KEEPALIVE and numerical proxy ip address) to get it to receive calls properly with my Time-Warner-Cable modem/router. I must say, however, that it had NO PROBLEMS from the start with my ASTERISK PBX at work. I also have put it on a static IP address so I always know where it is in my network. This works fine as well. DHCP also worked. Update #2: Well, I took this ATA up to work and it worked just fine on our Asterisk PBX for a week or two, even on incoming calls. So I decided to take it back home and change a few things and try again. So the bottom line was this: I PUT THE NUMERICAL IP-ADDRESS (4.59.156.116) OF SIP.TELASIP.COM (my provider) as the proxy instead of "sip.telasip.com", and turned ON all the NAT option NAT KEEP-ALIVE. I do not know which one fixed it, but IT SEEMS TO BE WORKING FINE NOW, including incoming calls and caller ID. (I turned have NAT MAPPING ENABLE on too, tho' I do not know what this means) I will continue to update this status if it changes. I give it just 4 stars for now, since I had to dink with it. (To Cisco: I checked to see that I had the correct DNS address over and over.) (find your provider's numerical IP-ADDRESS by going to the command line and: ping sip.telasip.com , it will tell you the numerical "dotted address". Update: Well this SPA112 worked fine for a while, then it started dropping inbound calls (so I did not notice it). I tried disabling Caller ID because of the ealier bug that was in the firmware. That did not fix it. Then I tried updating to the 1.4.1 firmware, and that did not fix it. So after you reboot it, it receives calls fine FOR A WHILE. Then it starts ringing once, and dropping the inbound calls. Cisco tech support is non-existent for such an inexpensive product. It either works for you or it does not. I will try using it on another carrier at work. First Review was good. Now not so: This ATA replaced a 10 year old SPA adapter that got hit by lightning. It had a quick setup screen! The only thing that was a little weird was that you had to hook up a telephone to find its DHCP address. Then you could go with your browser to that address to set it up. This was no problem for me, as I had done this before (you will have to read the manual to get this done). The quick browser setup screen worked right away, and it took me just 30 minutes to get going. It is quiet! It has caller ID! It is cheap and it works! Imagine that!
