This is discussion point here rather than a Help room poser.
Earlier this year I moved to BT Infinity-
The installer duly came and fixed up a new master socket,the router and Home Hub and then went round my 3 telephones and removed the filters-' You don't need these now ' he said its all dealt with in the new set up
Indeed all worked well no hang ups or drop outs
Returning home from a weeks absence - discovered the phone was dead - broad band ok - no phone- reported the same via mobile and the engineer tuned up next day muttering the statuary warning'If its your Kit you Pay' but after testing said no the fault is external - 37 metres away up the pole on the other side of the road.
Meanwhile yesterday the broadband failed also.
The man with the cherry picker turned up yesterday - fixed the problem up the pole in ten minutes and then came indoors to check the connections.
As he was doing so he asked where are the filters - you have to have them.
So conflicting advice?
Does the the Infinity man know something the linesman does not?
This seems to be one of those ongoing problems. I use TalkTalk, and when I have contacted their support team, its always a parrot fashion straight from the screen "Have you checked the filters". When I explain that my 'approved' system doesn't have external filters, confusion sets in, which then confirms the technical advisor isn't equipped to be technical!.
