Got a missed call from this number today, no voicemail left. I attempted to call back, and got "your call cannot be completed as dialed - please check the number and dial again."
I answered the phone and a live person said that he was calling "regarding an upcoming webcast" and asked to speak to a particular person in the office (that they must have obtained from our public web page). I said that person was unavailable and offered to take a message. The gentleman on the line said "no" and hung up.
