Well, only calls from fixed to fixed are cheaper ... all other combinations are cheaper with the mobile phone. As soon as the fixed line phone penetration drops, people rather use their mobile phones and dispose off the fixed line phone. Fixed line phones only make sense as long as people use copper for DSL. As soon as DSL users get their internet via TV cable or via FTTx, we're talking about VoIP anyway ... and as this is the same as what mobile is heading for (see VoLTE) ... there is no difference in technology anymore.

At least in Germany the trend is phone flatrates. It started in fixed net, but nowadays you can get your all-net flat (to any German fixed or mobile number) for mobile phone from ~20 EUR per month. I cannot get this price in a fixed line contract.

So times of "fixed is cheaper than mobile" are over ... at least in Germany and some northern european countries I know of.

Latest with the advent of AMR-WB in mobile phones (and operators), people will turn away from traditional 3.1kHz fixed line phones ...

Well, carriers will implement interconnection between IPv4 and IPv6.

I didn't say that fixed lines providing internet to peoples' premises will disappear ... just phone service on these connections. You might argue that people will eventually use their mobile phones in a hybrid mode (if at home, you're using the Wifi coverage to transport VoIP, on the road transport will be LTE/whatever).

 MvdV> Really? Can you still get ink for it?

Kyocera FS-1750 ... even original toner is still available.

Because you can?! ;)
And because it's cheaper than buying a native pulse-DTMF converter.
Alternatively you could buy a proper PBX ... which usually also supports

I agree for ISDN, but not for fax. Fax will survive as long as people have fixed line phones.

.... but for Google. ;)
