Andy - thanks for the shout out. There's definitely money to be made in voice as well. My focus was on video in this post. BTW - my son makes great use of the voice recording/messaging in Whatsapp - being just 8, he uses it quite a lot to communicate with his friends without "calling" them and without needing to type words.

Andy, Thanks for the kind words. Just to be clear - None of these vendors are a direct customer of mine at the moment for any specific project. I've written about it just because it was interesting and because CPaaS and its trends in general are important to me (as a consultant, I better know more about it that most others). It is also funny - I wanted to write a report about CPaaS with Chad Hart. We sniffed around, found out everyone things it is needed, but no one will be willing to purchase it. So we wrote a report about AI in RTC instead :-)
