Just RCG at this stage, but it's coming :)
Looks as thow if I want this I have to buy a new phone which will have to be one of those listed in the FAQ even though my Motorola phone shows a greyed out VOLTE switch in the settings menu.
This is the problem with mobile devices defining configuration in the device. it drives me insane. Carrier aggergation is the same.
