Excellent!
I wanted to replace my original Magic Jack and this device fit the bill perfectly. Incredibly easy to set up physically, though I thought the web account was a tad tricky....all ended well. Now, after many years of having Grand Central/Google Voice, I'm able to route free GV calls to my regular phones instead of depending on my main computer or my tablet, which often had echo issues, even while using closed headphones. My OBi200 didn't have any echo at all, and that is both a frustration saver, and even a relationship saver. My boss can now hear me clearly, as can friends and family. I subscribe to Comcast's 25mb internet service a la carte, and I've never seen any service degredation while making calls via VoIP.
I'll have to be sure to use a 2-jack splitter so I can use my fax machine. DO BE SURE to connect the power adapter to a UPS, along with the cable modem.
No, I don't have 911 service with this device, but I at least know the back line numbers for my 911 center. Small potatoes for me, but some reading this review may absolutely require 911 service, therefore a traditional landline may be a wiser move.
