  51. 51. Final words Non Confidential – Public © eXplanoTech Ltd. 51  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.
