This can be caused by incorrect wiring or a faulty filter.

Remove all telephone devices from the phone sockets in the property, plug the router into the master telephone socket via a filter, and test the connection, if there are still problems with the connection, try swapping out the filter for a different one.

If you are still having problems with your connection, please contact our support desk and we can look at resolving the situation.

If the above seems to fix the problem, plug each other telephone / Skybox you have back in (using a filter on each device) until you can isolate the device which may be causing the problems – if you have a faulty filter, please contact our support desk for a replacement.
