Summary: Check with your internet phone provider first. Some providers will only use their own configured SPA. It may be the exact same model as this one but they want their configuration loaded and will not use the one you bought. So before you spend the money, check in with them. However, the one I have from the phone vendor has been rock solid. Sound quality it good. Albeit all of this also does depends on your internet connection and your provider as well.
Summary: This is a great device for VOIP. It allows practically anything that you want to do voip related but beware: it's a very powerful device which has LOTS of options for configuring. But at the same time, that feature is at the same time the biggest flaw: it's complicated to make it work. In the other side, another great feature is that this is a GATEWAY which will allow you to build 'bridges' between pstn and voip with multiple configurations available.
Summary: I didn't even open up the package and returned it for a Obihai Obi110. I accidentally ordered it before doing enough research. I wanted to use google voice and have my POTS line plugged in as well, and be able to route over each one. I found that the Obi110 gets more updates, and that it works better with google voice. I'd check that product before buying this one.
Terrible Echo on the FXO; Get the Obihai 110 instead
16 August 2011
Summary: For the longest time, this was the only choice if you wanted a combination FXO/FXS device that did one FXO and one FXS. Users have constantly complained about echo on the FXO port, and my experience was that it was impossible to get the echo to go away. I followed all of Cisco's documentation on eliminating echo (including the guide referenced by Cisco in their "comment" on my review (below).
Summary: I love this device. It saves me a good amount of money and gives great voice quality. I have ordered two of these and sent them to my family and friends overseas. I assign the device a free call in number through IPKall and call them from my cellphone. I also configure one of the gateways for out calling and it all works just like magic. I'm in process of ordering a third device for myself now.
Summary: Excelente equipo para una pequeña empresa. Tiene una entrada de línea telefónica análoga y otra como salida análoga (Un FXO y un FXS), una conexión de LAN y otra de WAN. Tiene gran cantidad de parámetros para ajustar, que permiten hacer llamadas por internet según el plan de numeración y muchas otras cosas. No es un equipo para principiantes por la cantidad de opciones que tiene, pero es bueno para aprender telefonía VOIP.
Summary: This device does what it supposed to do. I use it to connect an IP PBX to a PSTN line. It works. There are a lot of configurable parameters, probably way too complicated for a non-technical person. Documentation is decent, but not great. Don't expect Cisco to put out any more firmware update on this product, as this product has been around for a long time. The first unit that I received was broken. I had to ship it back to Amazon and get a replacement.
Summary: i'm still trying to configure this thing and whenever i try to access the website i can't. it keeps on giving me an error. can you help me configure it. i rated this item just to get through, because since i haven't been able to set it, i don't know how it really works
