I know that different people not only have quite different preferences but also different working styles, but I generally agree with this.

IME the slight extra friction of initiating a call acts as a filter which means that I am less likely to ask colleagues either something which only saves me a few seconds, or to just start a nebulous discussion. Text chat is the right medium for both of these, even when in the office, as it's asynchronous and no one else has to hear it. When I call someone I tend to have at least a clear question or request for something that will make a significant different to what I can get done today.

The other argument against the benefits of face-to-face communication is that, unless everyone in your org works in the same city (or even, on the same floor - since most people don't walk around huge offices to ask colleagues quick questions), you should be practising with the online communications and finding good ways of working with them anyway. Otherwise fully distributed teams degrade into geographic silos, and teams with only a few remote people tend to just leave them out.
