I have been a friend of Dean Bubley's for quite a few years, and consider him one of the world's leading Blogalysts (an independent analyst who uses the blog format to share perspective, insight and opinion) This past week he took to task another respected analyst, Gabe Brown article, that surrounds VoLTE and IMS. Dean, who is usually mild-mannered clearly had a nerve struck.
The points Dean makes in his post are nothing new to be reading from him. I've been hearing those points (and reading them in his musings) for years, usually over a nice cold cocktail in one of London's better mixology establishments or over an ethnic meal.
IMS is a pipe-dream that continues to be pushed by some long time bureaucrats/technocrats inside the NEPs and the GSMA. And, VoLTE is really as Dean points out, a very big misnomer, as for now its going to be telephone calls over LTE, as the concept of voice as a service has yet to really be embraced by the mobile operators.
