Our landline service via the BT/Openreach network is not immune to failing. Often of late it has happened after they have accessed a cabinet in a nearby street and somehow managed to disturb/disconnect our connection. We too tend to just use our landline for broadband and have done so for some years now even though we pay for inclusive anytime calls. We do so not least because the line quality for calls is poor and has been for some time even though Openreach insist it is ok.
