The boundaries between the methods we use to communicate are gone.
We voice and video conference from our desk, our laptops, and our phones. We jump from text chat to voice to screen sharing, to collaboratively working on documents with a few clicks or taps. We may use handsets, softphones, or mobile apps. We use WiFi instead of our cellular network when we can. Our messages reach us when and where we want — by phone, email, or text.
