I think this is definitely a bit of self-selection. I find phone calls are still better for conducting complex business - not everything can (or should) be scripted using a form, and a phone call sometimes is much more efficient than chat or email. Video chat would be even better in some cases, but there's no standardized infrastructure for this. And even then, outside a corporate environment that has dedicated video conferencing rooms on both ends of the call, a phone call is often simpler.
