Customer Reviews
Nice for second line
I concur with Chih-Lin Ko's review (though I haven't tried using it with Google Voice): A solid, economical product that would be more useful if the analog FXO could be passed through by default, so that 911 and local 7-digit dialing always works. I would have liked being able to download/upload SIP settings, or store multiple SIP settings selectable by dialing *-something-something.
By default, the web interface is accessible only from the LAN pass-through, from whence you can make it visible to the whole network. You *might* be able to use this with web-authenticated internet (as in a hotel, for example) by connecting your laptop through the LAN pass-through. It is certainly small enough to pack in a travel bag.
I tacked it to the wall of my basement and use it for a second/FAX line and it works like an ace with a couple different SIP/VIOP providers (not Skype of course).
Simple and works well.
Setup took me a few minutes to figure out with my Gizmo5 account, but otherwise was a breeze. Works great all the time, call quality is very good, I'm quite happy with it. The box does emit a _very_ high pitched noise when it's powered on, but probably not even audible to anyone over 30 or so.
Best value, small form factor
This is the best and budget SIP box we can get in the market. Setup is easy if you read the instruction carefully on the Interactive Voice Response or IVR and http programming. The http programming is default turned off, you need to enable it in the IVR. I use this box for Gizmo and it works like a charm. Combine Gizmo with Google Voice, you got free domestic US call for both inbound and outbound (outbound need to use GV webpage to arrange the call to get unlimited minutes). I also own it's predecessor HT-386 for 4 years (also bought here), no problem at all. The only compliant is this box is default to SIP, secondary to PSTN. It will be nice if it has an option to have PSTN as default and SIP as secondary, then I can use them more efficiently. A simple example is if you have SIP as default, people will have hard time reach 911 or emergency call without knowing you have to press "*00" first. If it can be programmed to use PSTN first and SIP secondary, then this problem will be solved, not to mention the complication of the 911 dialing plan programming, which this box also lack of.
Works Great
Easy to setup. Does what I expected and more.
