My personal experience is that emails and written documents are how things actually get done, but sometimes we have to go through voice calls and in-person meetings in order to get that far. Those voice interactions felt like some sort of psychological barrier that couldn't be bypassed any other way, at least initially, but once I have opened up a non-voice channel, that's what we tend to use going forward.
