This number auto dials through many numbers on our
pbx system, we are going to block it because it leaves a
blank 12 second VM at every extension @ 2:00AM!

This number on my caller id lists:  ADBASE SYSTEMS. Their automated ghost calling would call me at all hours in the morning until I reported the number to the FCC at the end of last year.  Now it has started again at 6:07 am this morning.  Jeff, Qwest customer service rep. told me they can't do anything about it, because they are a Canada company.  Only to me, Canada does not have a PA area code!!!!!!
