Summary: Lots of options in the web interface. I've been using it for about a year now with no complaints. I have only had it hooked up to one phone on a short cord, but I'm interested in hooking it up to multiple phones that don't have additional power/amplification.
Summary: Using this with RingRoost.com and tied it into my office phone system. I can call the office from my Grandstream GXP1405 just by dialing 102. The office can call me just by picking up line 11 and dialing 101. No per minute cost either since the calls stay on RingRoost.com system. Easy to setup.
Summary: I used this to connect a fax to a VOIP-only phone setup. Setup was not straightforward since almost every VOIP provider's instructions reference older revisions of the device's firmware, and I had to guess at some settings. Now sending and receiving faxes works fine.
Summary: I've been using this device for just about a year now with no issues. The setup was a little tricky if I recall but in the past year I've never had to touch it. If it burnt out right now I'd buy another one.

Summary: So far this is working great. I have internet telephone service through onesuite.com. I call it my "try wait" phone. Calls don't always go through, and not all calls can come in. But I believe this is a function of the entire system and not the analog converter.
It was recommended to me and I expected great things

Summary: I never got this product to work as expected. It was recommended to me and I expected great things. If using it for just talk it worked pretty well but I need it to support Fax and Modem data. I never could get it to work right.
