BT Line Fault - Driving Me Insane!!
For the last couple of months I have been experiencing interference on my cordless phones whenever I make a call.
The noise can be heard in the background when making and receiving calls making it hard to hear people. In addition to the interference I sometimes experiencing a clicking noise. I carried out an automated line check which gave the all clear but wasn't happy with this so had an engineer come out today. The engineer checked both outside and in and can find no fault. He changed the face plate but still the problem exists. I have changed all the DSL filters, disconnected the router, fax machine and plugged the base station directly into the main socket and still experience the problem. I have even bought new cordless phones which has made no difference at all. Has anyone got any suggestions as to what the problem may be? I said to the engineer that I have had the same set-up (computer / router / fax) for years so I know it isn't the equipment otherwise the phone issues would have been in existence from the outset. I'm not sure what more I can do. |

The only way to prove this properly is to get yourself a known working corded phone. Remove the bottom plate on the BT socket and try making a call. If its noisy then yes it is a BT fault, if its clear then there is no fault with the line. Im afraid if the BT enginner did this test and found it to be clear you will be charged for the callout.
If the line is clear then start adding equipment. first thing will be the broadband, I have experinced with some cheaper cordless phones that they can pick up noise from the broadband circuit even though you have a good filter. With a friends phone I was convinced it was a faulty line until I checked with another phone then the noise dissapered. |

One thing to try.
Unplug your phone base unit from the filter it is in at the moment. Take a spare filter and plug that into the first. Then plug your phone into the second filter. Does that make any difference? By the way if your modem/router is plugged into the same socket make sure you keep that plugged into the first filter (ie the one plugged directly into the phone socket). If the base station is hyper sensitive to the ADSL signal then double filtering might just get rid of the noise. Not the most elegant solution admittedly though. Perhaps fitting one of those filtered face plates might do the job? It's entirely possible they contain better filters than the plug in type. |

**Update**
As suggested I bought a basic corded telephone and disconnected my fax, router and other connected devices such as Sky box. I plugged the corded phone into the main BT socket and there was no interference. I started to add my devices one by one and found that with everything plugged in the corded phone was less affected than the cordless phones. However, the inclusion of the fax which is connected via a splitter created some interference but nothing as noticeable as with the cordless phones. I have now disconnected the fax but also replaced the cordless phones with another brand and this has mostly resolved the problem. I say mostly as there is a very slight interference noise but nothing compared to before and the call quality is much better. The two sets of cordless phones I tried previously were Panasonic's and the new ones are from Siemens. I am wondering whether there is something within the components that Panasonic use that are more susceptible to reaction with wireless / fax devices. Thanks to all who have responded with help and suggestions. |

PS
I also carried out the suggestion to double filter but this made no difference. |
