Excellent product and customer support.
Review by confirmed purchaser
I removed long distance from our land line a couple of years ago and don't get reliable cell service where I live. I have relied on Skype for long distance. Unfortunately this meant sitting at the computer to make long distance calls. Call quality was usually ok but sometimes not. The RTX 4088 changed all that. The phone adapter plugs directly into my router (no computer needed) and sound quality is now the same as my local land line calls. Plus I can now move around with the phone just as a normal wireless phone. Great product!
