I love the web interface to adjust the settings. Much better than my previous Obihai 100 that died (after about 2 and a half years). Very happy with the low $30 price.Please note, when switching from Obihai to this Cisco (or other generic), my VOIP provider, PhonePower, required a manual set-up; the easy auto-registration wouldn’t work. Props definitely to PhonePower tech support, Eric, for helping me with my settings, even though the PhonePower website stated that manual configuration you were on your own. Make sure DNS is automatic, and type in your SIP username and password correctly!Read more 5 people found this helpful Helpful Comment Report abuseR. Robinson5.0 out of 5 starsAmazing device!August 1, 2018Package Type: Standard PackagingVerified PurchaseI’ve been using this device since Feb 2018 with VOIP.MS and have had very minor issues.Every 2-3 months I have to change SIP ports in order to continue using the device. VOIP.MS’s service department helps each time and I’m up and running in less than 10 minutes. VOIP.MS’s setup can be a little challenging, but their service department (Chat or Email) is great. They also have really good setup guides to assist you as well.In terms of cost of VOIP service, I’ve spent about $15 for a phone number and phone service with e911 since Feb 2018. Or roughly $2.50 a month.It’s been great with no regrets, highly recommend!Oct 2018: Device is still working great. Setup is super easy as most places provide documentation for this device because it is so popular.Read more 2 people found this helpful Helpful Comment Report abuseMike S.5.0 out of 5 starsHome phone service for $2.64/monthOctober 18, 2015Package Type: Standard PackagingVerified PurchaseWe dropped our land line several years ago when we decided it was insane to spend $40-50+ in service charges, fees, and taxes for a line that we barely used. However with growing children, we decided that we need a reliable way for them to call us (or 911) when they are home without us.It took me about 15 minutes to walk my way through configuring the Cisco SPA-112 phone adapter to work with the Asterisk package installed on my Synology DiskStation. (This was an easy pre-packaged install on Synology, but Asterisk can also be run on all sorts of things like a Raspberry Pi or a home PC.) The next step was purchasing a phone number through Flowroute and spending another 15 minutes or so configuring that into Asterisk. The end result is a reliable home phone that costs me under $3 dollars per month.The one thing I had to change was the default dial plan on the device. The default plan made the system pause for several seconds after dialing before the call would go through. I used the following dial plan setting to make 10-digit dialing fast and simple: ‘(0|[49]11|[2-8]xx[2-9]xxxxxx)’This will also work with other VoIP carriers, like Vonage, for those that want to spend more or simply don’t want to rely on figuring it out themselves. We are saving a ton of money by using it, so I consider it well worth the up-front investment of time to figure it out.Read more 4 people found this helpful Helpful Comment Report abuseA. GRAY4.0 out of 5 starsThis ATA replaced a 10 year old SPA adapter that …December 1, 2016Package Type: Standard PackagingVerified PurchaseUpdate #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 andthe 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 ( OF SIP.TELASIP.COM (my provider) as the proxy instead of ‘’, 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 , 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!Read more 11 people found this helpful Helpful Comment Report abusecg5.0 out of 5 starsUsed with PBXact on Prem SystemDecember 6, 2018Package Type: Standard PackagingVerified PurchaseStruggled with config at first until I found a review that stated that I need to specify the non standard port in the quick setup setting.notes:quick setup string to server = [X.X.X.X]:5160Dial Plan for three digit calling, 10 digit and 11 digit calls and forces call to start (default pbx is expecting a ‘send’ signal’ ((S0 equal no wait, S1 equals pause for other digits)):(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.|xxxS1|xxxxxxxxxxS1|xxxxxxxxxxxS0)Rock solid, users wanted to have some cordless handsets work with the new pbx, this ata allowed me to do that and the handsets can participate in our ring groups.Security system needed pots lines, this allowed me to get them dial tone within an half hour and being ip based I could get dial tone to device in different parts of my building using my existing network without running new cables.Very pleased with these units.Read more Helpful Comment Report abuseSee all 333 reviewsWrite a customer review Set up an Amazon Giveaway Amazon Giveaway allows you to run promotional giveaways in order to create buzz, reward your audience, and attract new followers and customers.
