    I ordered 2 of these & received them very quickly. The high quality of packaging was superb, the condition of the two laptops was mint. Everything was cleaned and ready for immediate use. The pricing was great, I got a discount for buying more than one. The appearance was better than described. Saved this seller will do business with them again!

    Replaced an old ATA

    I have used another ATA for about 6 years without any problems, but recently it started failing. Purchased this one and it arrived quickly, took a little effort to get it working with my router, but now that everything is set up right, the quality is outstanding. Much better than my old one. My router is designed for Voip and needed to be set right to make this unit work flawlessly.

    I set this up with an Asterisk server I use, and it went good. But the unit died within hours of use! It doesn’t turn on anymore! (the unit is the issue, not the power adapter. I tried other power adapters, and none worked.)

    Good phone adapter, beats phone and cable companies offers

    Don't know how this was shipped actually from Amazon Prime, although I ordered on eBay this item. I use VOIP dot MS service, it is low cost, easy to setup, allowing me to block junk callers. I have been using this kind of adapter for many years. It is great and reliable. VOIP's call rate is very reasonable. Its tech support has sample configuration that can be followed exactly to configure this adapter.

    Looks like a good product but don't buy it for Xfinity Voice

    This review is more about how this product works (does not work) with Xfinity voice than the product itself. It appears to be a well-made product, however, if you bought it to work with Xfinity voice using any plain modem/router, you may be disappointed. I bought this adapter (and a cable modem) hoping to not have to lease Xfinity's modem with voice any more, however, Xfinity told me that this simple VoIP ATA device does not work on their network which requires an eMTA (embedded multimedia terminal adapter) phone jack. You may have better luck and/or get a more competent Xfinity tech when try to activate it, but it didn't work for me. I'm buying a Netgear modem with phone (CM500V) that is approved by Xfinity -- I just don't want to pay Comcast $10 a month for modem lease. I gave this ...

    Great Analog Adapter for FAX

    I have deployed 3 of these so far to connect Fax machines to my IP-PBX. Set up is simple, and performance has been flawless. Best and least expensive adapter I have found. It has two analog ports, so I have also been able to deploy inexpensive cordless phones as extensions as well. (Freepbx via Flowroute)
