BLUFF: Should I wait three to four weeks to conduct my Internal Customer Interviews face to face, or do them by phone now? 

Just started a new job. My boss and most of the team I will work with is three states away. It will be three to four weeks before I go out to meet with them all face to face. Right now the only two I've met face to face are my boss and her boss.

Do you think I should start Internal Customer Interviews now, by phone or should I wait and do them face to face when I go meet them in person?
