At Microsoft, we allow anyone to call in and be transferred to a particular person. This means we often don't know who the caller is. If it is a call from within Microsoft, the phone display shows woh the call is coming from. In the U.S., it is not common to answer the phone and say we will call you back. Instead, when we are busy or prefer to talk later, it is most common to not answer and have the caller leave a voice message for the call to be returned. In fact, most people in the U.S. would find it negative to get an answer but then have the person say that they will call you back, and people here would prefer to just leave a voice message if the person cannot speak at that time. This obviously varies in different cultures. What should have been done is to turn the phone ringer off before the video started.
