Earlier this month, I attended and chaired the first day of the LTE Voice Summit in London. Similar to the last 2 years, there was plenty of evidence of VoLTE progressing across multiple regions. There weren’t any new big topics—items like VoWiFi and NFV are well understood and underway—and for the most part, discussions centered around progress being made on adoption. Roaming was the only area that still elicited healthy debate on which approach to take and why. As of 30 September 2016, 86 operators have launched commercial VoLTE services across 49 countries.
