About every other day, or so, I get a call from this number.  The line stays active for about 60 seconds there is no activity from the other end upon the 'hello' to indicate I have answered the line.  Once the initiating caller disconnects the call, I have repeatedly called the number back and continue to get an automated outbound message indicating the line is not an active number and if I should feel I had reached the recording in error I should disconnect the call and try again.  The number belongs to Pacific Telecommunications Group and is no longer in service.  I want these calls to stop.  I have my number registered on the state and national no call list but there are those numbers that seem to slip through the cracks of the system.
