- Unplug everything that’s plugged into your phone sockets, including Sky boxes and other equipment.
- Plug a corded phone into the master socket (the master socket’s the first socket where the phone line comes into your home).
- Try to make a call.
If you then hear a dial tone, there’s no problem with the line itself. The problem’s wiring, microfilters or your equipment. To find out which is the culprit, plug in one device, then check for a dial tone. Repeat this with every device, checking for a dial tone each time, until you find the one that’s causing the problem.
If you don’t hear a dial tone after you’ve done that, try using our phone trooubleshooter to see if there’s a problem at the exchange.
