770-615-3243

I've been getting a lot of calls from the 770 area code lately.  This one like the others says nothing then hangs up.

I'm getting hang-up calls from this number also. Calls back to this number result in busy signal.

Portland, Oregon. Received a call from this number on my cell at 9:05am. Did not answer, they did not leave message.

Got a call.  Didn't answer. They didn't leave a message

Received a call but did not answer. Caller ID shows company "Intelligent Data". I have never received this one before. Usually its the slimey car insurance people... neigh, criminal scum bag car people.

Received a call from this number.  Man from Network World magazine, wanting to send out a White Paper from Akamai.

Got a call from "Texas Instruments"on this number. TI is a semiconductor company I actually have signed up with.  

Doing a little research, the number actually appears to belong to "Intelligent Data Services", a business to business company- aka marketing. TI hired them to flog some leads and drum up new business, presumably.

They wanted to send me a TI newsletter. OF course who knows who it really was!
