Hi, I am having a problem with my land line phone which is not ringing for incoming calls. Phone is connected to a wall socket not the hub. The phone doesn’t ring for incoming calls but if I lift the handset the call connects & outgoing calls are fine. Have tested with multiple handsets but still the phone is not ringing and the handset I have works on my BT line so clearly it is not faulty. I have checked the line status and all appears to be OK. Is this a fault with the Virgin line or the local box connections?
