My understanding is that VoLTE is signaled using SIP.  I don't know how 
the media moves.  I think they tried to avoid re-inventing the wheel. 
Most of the "phone" guys are slinging a lot of inter-network calls via 
IP these days, anyway.

Believe it or not, several of the major wireless and even wireline 
carriers seem to do this to some degree, though my evidence is 
anecdotal.  They don't seem to drop when you exceed your dollop, though, 
but rather re-mark.
