Final words

The various VoLTE interoperability issues between different operators is mostly due to regulatory and interconnection issues. Will get resolved shortly

There is no consensus on how to charge for Video. SK Telecom prefers per minute while Verizon prefers by data volume

Roaming is another area of discussion. NTT Docomo and SK Telecom prefer S8 based home routing because its simpler and faster

Voice over WiFi (VoWiFi) specs coming from GSMA in Q4 2014

VoLTE functionality is generally in the chipset hence is more efficient than other OTT VoIP applications. RCS is a downloadable/native client.
