Doubt that'll work if the problems are elsewhere

Apparently all it does is try to reduce the interference from the "bell wire", which isn't used with modern phones so the simplest thing to do is disconnect it yourself if that's the problem: User Posted Link

"Cougar" seems to offer good advice in the comments: "As sike222 says, all the iPlate does is isolate the bell wire. The bell wire was used historically to make the old-style dial phones ring, and is still used today by some fax machines and analogue (dial-up) modems.

The problem is that on modern ADSL-enabled connections, the bell wire acts like a dirty great big aerial for all the electricial interference kicking about in your house. If you don't have any of the devices above then you're safe to disconnect it. This will have exactly the same effect as buying the iPlate, and saves you fourteen quid.

The bell wire is connected to pin 3 on the back of the Master socket, and should be coloured orange with a white stripe unless your phone cabling was fitted by someone other than BT or is really old. (Hit Google for more in-depth instructions).

The caveat here is if you mess it up, BT will charge you the soul of your first born in order to come and sort it out. This is why the iPlate exists, it's to stop the enthusiastically ham-fisted from trashing their wiring and then complaining to BT that "you told me to do this and now it doesn't work." If the thought of having to wire a plug used to give you a cold sweat, you're probably best off paying for the plate as it's nice and reversable. On the other hand, if you're quite comfortable with a screwdriver, can count to three and aren't orange-green-blue colour blind then there's absolutely no reason to spend money on the iPlate. "
