Who's counting carbon dioxide emissions?
Yes, I've been through this process already, in Germany.
When I last changed my setup, I was informed that VOIP was all that was available. That means that tens of millions of households have to leave routers uselessly burning electricity 24 hours a day, on the off-chance somebody might call in the next few minutes. That must be quite a few power stations worth of juice.
And then there's the degradation in setting up. Previously, you just had to buy a handset, plug it into the wall, and it worked. Now you've got to _configure_ something, namely a router. No problem for me, but it "earns" the telecom compainies a fair bit from those who can't do it themselves. And those handsets weren't, in the main, crackable over the telephone network. Who'd say the same about their router, these days?
