Call from (404) 220-7655  Atlanta GA, Didn't leave a message

Pretended to be clearwire. I called clearwire back and they said that isn't there number so they reported to fraud department

I received a call from 404-220-7655 I answered.  There was music playing and a phone ring tone, Then call waiting with another call from the same number while I was still listening to the music on the first call. I have no idea what they wanted, twice.

Received a call from 404-220-7655 showed Atlanta, Ga. on caller id. did not answer figured it was another telemarketing trick by showing the city, state.

Received a call...didn't answer it...they didn't leave a message. I also have Clearwire like previous poster "Joe Billie Bobbie from ak." Maybe there is a connection?
