We've been forced to swap from our analogue landline to IP phone Fibre (ie a dongle in the back of our router etc) and though the fibre landline seems to work (gets dial tone, calls out) it doesn't ring when called.
Anyone have any clues on why it's not ringing?
Old phones (early 2000's and before) may require the presence of a 'ringing capacitor' (included as part of the master socket on the analogue telephone network, not present on the hub connection).
Cheap corded phone, no caller display, from the likes of Argos, Currys etc. costs £10-ish. Simple cordless phone, one handset about £30-ish. Alternatively borrow a phone from a friend, family, neighbour and check the phone connection from the hub with a different (modern) phone.
If you happen to have an old ADSL microfilter about the home, connect that to the VM adapter and plug the old phone into the microfilter and try your old corded phone. If your old phone rings, then you need a new phone. Using the ADSL microfilter is only suitable for test purposes as it is not designed for this type of connection.
Your technician visit might cost you £25 for nothing if your old phone turns out to be the problem.
