Not sure where to get help on this, and have sat on the phone to BT in a queue on numerous calls but never get to speak to anyone.

One day our BT landline phone stopped working, ie no dial tone. It is currently plugged into a secondary socket which is hard wired off of the main stocket where the core cables come in from outside. I am not using an extension cable.

Both main and secondary sockets have microfilters on them and had worked fine up to this point. The situation is as follows. With all equipment disconnected the phone works fine in both sockets. Putting a microfilter on just one socket and then connecting the phone through the microfilter works fine. But the moment two microfilters are connected no dial tone is available.

Anyone have any ideas here?

For completion when it was working fine we had sky and broadband into the microfilter on the main socket, then a phone in the microfilter on the extension. For testing I have not conneceted the sky or broadband cables.
 
From my work in Telecomms I would certainly start by replacing the Microfilters They are very cheap and you could find a 5 quid investment solves your problem.

If not them at least you have spares for when they inevitably do go wrong.

Anything beyond that I am pretty sure would be out of your hands to fix.

Off the top of my head the only other thing beyond bad filters that can cause what you are talking about would be a change of wiring and I'm assuming you have not fiddled with that so the most probable fault if it is a wiring issue would be cracked shielding has let water get into the wires outside and caused a short.

That would be up to BT to sort out though.
 
Actually I have rewired the wiring from the main socket to the extension, but nit the main core socket. Unfortunately the symptoms after are the same as before. I will try and get some more microfilters today and see if it helps.
 
I see my thread was moved to Internet connectivity sub forum. Although midly related, my broadband has always worked fine.
Anyway, new microfilters bought and same problem. Here is the interesting part. All microfilters removed, Sky line in the main socket, pone in the second and same problem. So issue seems to be having Sky plugged in.. With or without microfilter. Any ideas?
 
is probably faulty then...we've had a few issues with Sky and substandard connections (ie reall connections not internet)
 
Yeah, I'll see if I can find a cable around the house somewhere. Starting to become an annoying and costly problem to fix.
