Perfect for our application. I have Vonage running on our home telephone network. However, we purchased a 1960 era Stromberg Carlson 500 rotary dial phone and have it placed where there is no phone outlet. The InstaJack works perfectly, allowing the old phone to send (pulse dialing) and receive (with attendant old timey bell) calls. I have the Instajack transmitter installed in an upstairs bedroom where there was an empty phone jack and the other Instajack piece installed downstairs where the phone is located. Ain't technology grand!

For me, this product works splendidly. There is a little hitch that may cause some users frustration: I think this product is not some sort of "wireless phone extension," but it rather sends signals over your existing house wiring. If you have the base and receiver plugged into the same branch, it will work. If not, it won't. This is why I believe some outlets in my house work, while others do not. Thankfully, the outlet near where I want the receiver to be happens to be the same branch as one near a telephone jack. It also explains why they tell you not to use any sort of filter, surge suppressor, or even an extension cord for either the base or receiver. One way to be relatively certain that this product will work for you is to go down to your circuit or fuse box. If the two outlets are controlled by the same breaker/fuse, it will almost certainly work. If not, it might. The product does have an indicator light to tell you if it is connected, which is a great convenience if you don't want to analyze your home wiring.

Waw able to set this up so that \i have a wireless Fax line from the back house to the front house with no issues

Works as described. You have to read the description. It seems most of the negative reviews are people who ordered the wrong product for their needs. This one is for a voice line. If you want to bridge a data line (fax or modem) there are others designed for that. The only other thing is that you have to plug it directly into an outlet. It will not work if plugged into a power strip or surge protector..

Great product! Highly recommended! Was able to connect landline to a building that was 150+ feet away from the house! We do hear static on the line, but I think that has to do with our electric line DSL interference... the device itself if placed on the proper electric line without interference should world flawlessly for 150 - 200 feet distance, which is what I have tested!
