I simply don't place calls via the PSTN; why the heck would I ++? I can't find a single case where's it's cheaper to use the steam phone, so I don't.True enough, but it is well worth looking at the deals offered by the Betamax group. They have loads of similar services with different prices and different names. But basically you buy a 10 euro top-up which gives you free calls to landlines for four months. If there is any credit left after 120 days (calls to mobiles are about 6 or 7 cents a minute) you use that to pay 1c per minute for calls to landlines. For me, this means my calls cost about 25 euros per year. Yes, all of them! See http://backsla.sh/betamax for a list of the confusing array of Betamax products.
Incoming calls? Sipgate are fine.
BT are a bunch of Messerschmitts (or some kind of 'plane) => place two (ideally, free) calls per month via the PSTN or BT'll charge you. You have been warned. Oh, and don't forget to get their Line Rental Saver package to pay for the line up front -- £129 for a year. That's all those Fokkers will get from me.Better still, go elsewhere. Switch to Primus Saver for your line rental and pay about £6.30 per month. See http://www.moneysavingexpert.com/phones/home-phone-c... Their call charges are a bit steep, but you won't be making any calls through them!
