I think a couple of those assumptions show there are some things that TheReg reporter doesn't quite understand, like the termination fees

UM are also developing a convergence service/product combining VoIP with GSM/3G. If roaming data rates come down soon, I'm sure most of the roaming discounters will offer VoIP-over-3G (at least for outgoing calls) instead of the unreliable callback solutions. Beyond that it would make sense to route incoming and outgoing calls through wifi, if available. The Austrian operator A1 already offers a service called "A1 over IP", which allows receiving calls towards their cellular number through VoIP, so A1 customers can evade roaming fees if they have internet access and some VoIP device. Of course they can place outgoing calls at lower rates through "A1 over IP", too.
