What I see in this thread is that the OP came just to flame Obi, then left it at that.
I am not a network engineer - I am also an Obi user for years now - I have run into some problems that I needed help with.
Perhaps I am favourably biased, BUT:
There are some wonderfully generous, helpful folks here and in most of my situations I have been able to get great help right in this forum from other really helpful users here.
My only exception, problem-solving wise, here - has literally been with one I just recently posted that brought no real help a'tall.
But 2 thoughts alter that as well:
1.
The problems seem to have vanished all on their own.
2.
Maybe they were so odd that nobody else had those same ones before.
As an Obi user who has no need for either a landline or a cellular phone anymore, the notion of having a real phone that just uses my broadband connection pleases me immensely.
So I close here thusly:
You can please some folks SOME of the time - but nobody can please ALL of the folks ALL of the time.
And life goes on...
