Not for the faint of heart...
Although VoIP is slowly moving more and more mainstream, a device as flexible and as configurable as the Linksys SPA3102 is not for anyone who either is not comfortable with programming the ATA with your VoIP provider's SIP settings or coming up with an approprate dial plan for your device that is compatible with your provider.

Very flexible FXS/FXO
The SPA3102 gives you both an FXS port (for a phone) and an FXO port (for a phone line), it's two devices in one box. Each device can operate independently or can be made to interact with the other. More >>

Just don't use the PSTN
I generally like this product, but there's one problem with it.

Likes: Lots of options, VOIP stuff (the most important stuff) works fine. More >>

Great Product!!
This is a great product with tons of features (which actually work)! I bought the second one (for a different location) after using the first one for six months without any problems. More >>
