Cisco SPA112 2 Port Phone Adapter

It did everything it was suppose to, happy with my purchase

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: admin6) 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).

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 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 (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!

nice And Reliable, Easy to program IP to Lanline Converter which support 2 Devices.ProsLED Lights gives visual feedback on Connection of 2 landline, 1 LAN, 1 PowerEasy to ConfigureBlack colour is less prone to dust marksImproved Power AdapterConsThey must allow Micro USB Connector with Mobile Charger or PC based Power to save cost.

I installed this when my original device died without notice, and it has been stable and mostly trouble free. I have had network issues that caused me to reboot my router and all the devices connected but I do not blame the adapter for the problem.

Inutile discutere sulla qualità di un marchio, Cisco, che non ha bisogno di presentazioni. Il prodotto è vecchiotto, soprattutto perché a quanto vedo non è più così necessario come lo era qualche anno fa. Le aziende sono passate ai telefoni ip, i nuovi router consentono di gestire la fonia su voip e di effettuare il ribaltamento dell’impianto telefononico di casa: dunque il prodotto non ha avuto necessità di essere rinnovato.Nel mio caso, non potendo portare un doppino dal mio modem VDSL a dove mi serviva ma vi arrivava un cavo ethernet (in precedenza usavo una delle coppie del cavo ma avevo così ridotto la velocità a 100MBit/s e creando un collo di bottiglia) ho fatto ricorso a questo ATA. Come sempre, quando si acquista un prodotto, ci si chiede se sarà compatibile con il proprio setup..se i protocolli dei propri apparati sono proprietari spesso non sono interoperabili. In particolare avrei voluto sapere se era possibile collegare questo ATA al mio fritz!Box 7530, specie su una subnet differente. Ebbene: si. Ed è stato semplicissimo, funzionando al primo colpo. Dunque un plauso a Cisco per questo SPA112 ed ad AVM per lo stupefacente 7530!

Funciona muy bien pero el configurarlo la primera vez es un suplicio.Para empezar hay que conectarlo a un router con DHCP activado, luego conectarle el teléfono y pulsar **** y luego 110# para que te diga que IP tiene en perfecto ingles. Luego si tienes suerte, pones esa IP en el navegador (no uses Firefox la primera vez), pones user/pass y ya lo puedes configurar con los valores de tu compañía VoIP.En mi caso, como tenia un firm tan antiguo, aunque me asignaba IP el router de fibra no era capaz de verlo, por lo que no me podía conectar a él. La solución fue usar un viejo router de ADSL, conectar el adaptador SPA112 y conectar un ordenador al router ADSL para cambiarle el firm a la última versión (1.4.1 SR1 ). Una vez hecho esto, el router de fibra ya lo ve y te puedes conectar sin ningún problema desde cualquier equipo y con cualquier navegador ya que se ha solucionado un bug que impide a Firefox la conexión con algún firm antiguo.Una vez has terminado de configurarlo con 1 o 2 lineas SIP, te olvidas de él. Puedes dejar el resto de la configuración por defecto que el equipo funciona perfectamente.Si no quieres conectar un teléfono en el conector del SPA112 y quieres dejar los terminales donde los tenias previamente de la instalación de teléfono convencional, conectas un cable telefónico en el puerto que hayas configurado (en mi caso el 1) y luego a la roseta y ya puedo usar el terminal inalámbrico que tengo conectado a una roseta en el salón.Yo lo he comprado para configurar una linea de Netelip y la fibra de Pepephone, ya que el router suministrado (F680) va capado y no se tiene acceso a la configuración SIP aunque el router sea capaz de gestionar la linea VoIP.Recomendado.

It has loads of options. The web UI is a little slow and its a little lite on manuals.
