Just received call from this number..no message..just a busy signal.

Just received a call from this number.  As with prior postings, the lady had a foreign (asian sounding) accent saying they had a medical alert product "like the lady that falls on TV".  She asked if I would be interested in hearing about their product.  I asked to be put on their do not call list.  I am already on the National Do Not Call Registry, so I'm not sure just why I was called in the first place!

I just got the same call from this number.  After I said "hello" there was a pause, then an elderly sounding lady said "goodbye" and hung up.  Weird!!  I would love to have this number tracked.
