I bought this so I could use another phone and jack in my house after switching to Vonage. I was unable to use the other jacks in my house because my local phone company did some funky wiring and so the wiring quick fix which Vonage advertises did/will not work. Anyway, I read several previous reviews warning that this RCA product may not work depending on the wiring in your house. I took a chance anyway, and those reviews turned out to be correct. The wireless phone jack system DOES work, just not very well. There is a very loud hum/static noise on the phone which I've plugged into the jack. I'm guessing it is because the phone jack which I've plugged it into is not on the same circuit as my main Vonage phone (as mentioned in one of the reviews I'd read). But, at least now I can answer a phone at the opposite end of my house from my main Vonage phone and can tell the caller I need to switch to another phone. So, it's not perfect, but it suits my needs . . .
