my virgin phone line let’s me ring out to make a phone call. But when I try to ring the home phone it rings once with a crackling noise then rings off.yet when I do a check it says no problems with my services. I switched my tv box off then back on again but still the same.
Do you have a normal POTS line (normal phone wall socket) or does your phone connect to the back of your broadband hub?
If it is a POTS line then this could possibly be a line trip, a tech would need to visit to swap out the phone socket on the wall. If you are in an area that provides voice over your modem, then they will just remotely migrate you to a DOCSIS line, they will send an adaptor in the post.
If you line is via the broadband hub, then try rebooting the hub. If that fails do a FULL default settings reset by pressing the reset button at the back of the hub till it resets.
At last virgin sorted out our phone that went from crackling line that would ring in to the house phone was but rang off after one ring to completely no tone at all. Appears rain got into the inside line box, from a exposed broken sealed external entry point to the inside telephone line coursing damp than corrosion. New inside line box and reconnected to spare line from the virgin brown box it’s know fixed.
