Facebook’s ambitions aren’t limited to messaging, the company wants to dominate voice communication as well, and it’s certainly off to a good start.

Messenger is already dominant in America, while Facebook-owned WhatsApp dominates pretty much everywhere else, it’s just China that Facebook is struggling with.
