We have BT Infinity, and since it was installed we have had a lot of interference on the phone line. At first we thought it was a duff phone, but having tried a different handset we think it's something to do with the set up. Using a straightforward wired phone it sounds a bit as though we've got a crossed line - faint talking in the background. Our usual multi-handset wireless phone just sounds rather muffled with a lot of interference.
Under the old broadband system we had filters, but with this setup there are no filters fitted, and our old ones won't fit the DSL socket. The main phone base unit it situated some distance from the broadband box, connected via an extension socket. Putting a filter in to this socket did seem to help the situation, but it wasn't ideal.
So, what filtering should we have in the system? Could it be something else? Since logging on today to try and get some ideas with how to deal with this I've seen things about accelerators - what are they and is that what we need??
infinity is fitted with a filter built into the master socket an no other filters are required. if you try the quiet line test dial 17070 option 2 and there is noise then you need to report a phone fault to 151
Thanks - we've tried it and it sounds like there's some radio interference (apparently Millwall are winning!). I'll report it as a fault.
If you're getting overhearing the pairs for your line have come into contact with another pair, I wouldn't be at all surprised if the fault is in the cabinet.
