Terence which country are you in? In the UK the Telco takes the line down
after a minute or so, and as others have reported this patch simply raises
it again which isn't clever. It sounds like your telco has (recently) taken
to dropping the line in the middle of the night. Of course very unlikely
you can find anyone in telco who will actually tell you what they are
doing. This patch would fix it for you, but as footplus mentions this isn't
the correct way forward.
