This number is a real pain in the neck. It is an Allentown, PA location, but when you call, the line is busy. It must be some nut who has nothing better to do than call and listen to those who may answer the phone instead of allowing it to go to the answering machine or voice mail. There is no message, so they just hang up. If your phone has the capacity of "phone block", place the number on your phone's list. Another option is to answer these annoying callers and press a couple of numbers on your end of the line and beep as much as you can into their ear. That will work for a bit. Have a loud horn ready to blast into the phone when they call. Don't give them the satisfaction of hearing your voice.
