One of our first guest experts was a CBS morning show producer who I persuaded to come on.
I was pinching nickels back then so we used FreeConferenceCall.com. The members were pumped, they were all on the line early. And then the producer didn’t dial in! I called her on her cell, and she casually said, "I thought it didn’t start for another hour . . ."
I didn’t trust that she’d navigate the dial-in so I kept her on the line and literally typed in all nine members’ phone numbers, one at a time, into my iPhone 3 and merged the call! After the late start, it turned out great.
