Hi everyone, I have a problem which I would appreciate any contributions to help.
When I make a voice call on my corded landline, I notice that the line hisses and crackles, which can vary from faint to really quite loud, but it is always there. I have tried a number of remedies, including:
- plugging my corded phone into the test socket on the main BT phone socket - no hissing
- changed all the adsl filters in the flat - still hissing
- bought a new router - still hissing
But...I have noticed that when I unplugged the router, the hissing stopped (hence I bought a new router as I thought the old one had had it). It is really bugging me. So in a nut shell the phone line is crystal when there is no router plugged in, but when it is it hisses. My ISP is Virgin Media.
Any help much appreciated.
