We've had O2 "business" broadband for quite a while now. We have a new home, and I removed the bellwire early on to improve ADSL reception. When we moved in and dug out our very old DECT phones, they were rubbish. Noisy, feint voice, just terrible. So we ditched them and put in our regular old phone...
More recently we tried some brand new DECT phones. Panasonic and AN Other brand I can't recall.
When the DECT phone is plugged into the wall socked, any wall socket (we have the master and one extension) the line is fine.
When we plug the phone into a microfilter, regardless of brand (I shelled out on a new XF-1e as apparently they do amazing things) we get a great deal of line noise, and the phone is extremely quiet. Unusably quiet voices, and unbearably loud "noise" (hiss).
Now, this happens even if we disconnect and switch off the modem and all other wireless enabled products in the house.
No microfilter, perfect, microfilter, unusable.
Our regular old plug in BT phone works whatever the microfilter situation.
It seems that the microfilter(s) cause the noise, but six (yes, six) microfilters, including a brand new one, cannot be faulty. Where do I go from here?!
