So basically, I have 2 lines (or at least one line which is (multiplexed or whatever?) to give 2 lines). Now the first one is fine, both phone and broadband working no problems whatsoever.
The second line has a really bad crackling noise on the phone when the broadband modem is plugged in and also whenever you pick up the phone (to make or receive a call) the internet cuts out for around a minute. After a few seconds you hear the fax type noises starting again as it reconnects.
I've tried 3 phones, 5 filters and 2 routers all plugged into the test socket so I think I've done my bit eliminating the problem from this end. I don't seem to be getting anywhere with Talktalk though, the latest they've told me is that a BT engineer has been working on it at the exchange for the last 4 days straight without even taking a break!!! Clearly they're just talking out of their backsides. No offence to any other country but every time I have to deal with a foreign call centre and they just spout rubbish every time!!! Probably not their fault, they've got families to feed etc. Companies shouldn't be cheap and outsource this stuff.
Anyway, anyone got any technical knowledge that might help me fix this? Talktalk can't decide between themselves whether it's a phone problem or a broadband problem. The initial guy I spoke to said there's a high voltage on the line which is the likely result of two wires touching each other at the exchange, sounds like it would cause the problems I've got to me.
Now, seeing as the line is shared and the first has no problems then surely the only place a problem could be is on the few inches of wire in my house from the first socket and the few metres of wire in the exchange? Can't see what takes them so long to fix?
