As a VOIP reseller I only use this adapter. There is really no better adapter on the market.
I sell mine preconfigured so it is just a simple plug and play but even for a novice this is pretty easy to setup.
Supported by nearly all voip service providers and offers 2 phone lines, custom ring tones and a1 port router that works very well if needed.
Calls are crisp and clear with no chatter or lag, fax abilities if needed. My only gripe is it never holds the time and date should you unplug the device.

I used this little device to rid my household of a traditional phone and moved to VoIP. Using a SIP provider of my choice, I'm down to a $3 a month phone bill and I still have e911 and call display. Setup is technically challenging, but most SIP providers have plenty of instructions to help you along.
Phone call quality is mostly good despite having limited QoS control. When you take the savings into account though, it's hard to beat moving to VoIP.
