Who called from 9896248438

Received a 'Obama announcement' recording when I answered.  After researching the number, it appears the entire block of numbers 989-624-XXXX (equal to 9,999 individual numbers) belongs to the Ameritech exchange in Saginaw, Michigan.  So, when you see area code 989 and the prefix 624, ignore the number.

Got a call from these phone pests but no message.

Constantly receive calls from this number but no messages left and when I try to call the number back it says the number is invalid. Mmmm can we say scam!!!!

My new tactic: Answer the phone but don't say anything.

Robodialers seem to respond to "Hello?" If you don't respond, they don't. This one hung up after 22 seconds of silence. Hopefully they add me to a "This isn't a person" list. (I can dream!)

Humans get confused and start the conversation - and then I tell them all KINDS of things.
* Take me off the list.
* "This is Sergeant xxx, who am I speaking to?" (I used to be military - I can do that if I want!)
* "What are you wearing?"

They just called me at 903AM central time.  Did not answer, no message left
