said by EPS:Correct me if I'm wrong, but aren't 4G-type network technologies like WiMax and LTE expected to be all-IP networks, essentially meaning that all mobile conversations will be mobile VoIP?
Though I suppose they could do what was done with EV-DO (which has no specific voice layer) and simply use pre-existing networks (CDMA2000 in the case of EV-DO) with the data network as an overlay used only when using data.
On 4G networks, yes, all calls will be VoIP, the question is, will any VoIP services other than 4G provider VoIP get the crucial QOS priority? Without it 3rd party VoIP is useless.
